Mac os intel fortran: idb works but frequently "Thread received signal ILL" or "BUS"

[mattnotting]

I used "ifort -w -g -save-temps -no_pie" to compile my program under Mac os 10.7.2. My intel fortran version is Compose XE 2011. This time idb can be started because of "-no_pie". However, under idb, when I "next/step in" my excutables step by step, it is frequently and unexpectedly interrupted by "Thread received signal ILL" or "Thread received signal BUS", or something like that. Interestingly, the excutables generated by ifort can run smoothly and achieve the correct results without any problems.So then I chose a suse linux system and still use intel fortran but 9.0 version, idb can work smoothly and never receives any signals like "ILL" or "BUS". So I guess it is the problem of Composer 2011 or Mac OS 10.7.Who can help me? Thanks in advance.Jianghui

have you tried compiling with -heap-arrays as described here: http://software.intel.com/en-us/articles/determining-root-cause-of-sigsegv-or-sigbus-errors/

[mattnotting]

Yes, I've tried that. But the problems are still there.

I note that when I run my executables, there are no such problems. These errors only occur when I use idb to debug my program.

There is a bug against stepping with IDB on Lion. DPD200176973. Here is the description, does this sound similar to what you are seeing? And you are using the latest 12.1 Composer XE 2011 Update 8 compiler, correct?

"no_pie helps to load the executable in idb and I can set a break point or run it. However, I don't seem to be able to step it (step or next). It just hangs. When I try stepi or nexti, it doesn't hang, but I only seem to step to the location where I have my breakpoint. If I remove the breakpoint and continue it exits "

Hello Jianghui,

that's an interesting sighting. Do you see this behavior with simpler applications, you could provide, as well?
If yes, I'd like to ask you to provide the source + binary for which you see those problems. Our debugger engineers can then try to reproduce the problem. They did not hear about problems like that so far.

Thank you very much,

Georg Zitzlsberger

[mattnotting]

Something like this. However, when I try stepi or nexti, it still received signal BUS or ILL. Even if I removed the breakpoints and continue, it still receved BUS and ILL.

I will attach a simple code for you to test. I think the problem is related to too large temporary array.

[mattnotting]

Hello Georg,

I attached two files here: fout.f90 (main program) and sps.f90 (called subroutine). I used "ifort -w -g -save-temps -no_pie fout.f90 sps.f90 -o fout" to complie them. I then use "idb ./fout" to debug them. NOTE: my Mac os is 10.7.2 and my intel fortran is a trial version Composer XE 2011 (12.1.2).

After you enter idb environment, you can set "stop at 7", namely the first call of sps. Then enter "run". As expected, the program will stop at the 7th line. Then you can enter "next". You will see that

Thread received signal BUS

The "next" command was not completed.

stopped at [subroutine fout():6 0x0000000100000c6e]

6 allocate(a(2000,2000))

If you add "-heap-arrays" in ifort to compile them, you can repeat the above debug process. After "next", the debugger is fine. Then continue to enter a "next", you will see

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

Thread received signal BUS

...

I need to note that if I don't debug this program, I just run "./fout". THe program can run smoothly.

I guess the problem is the repeated call of sps, a large allocagted array and a transformation of 2-d array to 1-d array when call sps.

Looking forward to your reply. I'm working on a big project. It's quite urgent. THanks.

Jianghui

[mattnotting]

Hi Georg, I add some more files, including the binaries you asked for. Jianghui

[Georg_Z_Intel]

Hello Jianghui,

thank you!

I'll talk with the responsible engineer this afternoon. Let's hope we can reproduce it on our side. We'll start with the binary you're about to provide have provided.

Best regards,

Georg Zitzlsberger

[mattnotting]

Goerg, could I know the progress of the solution? Thanks a lot. Jianghui

[Georg_Z_Intel]

Hello Jianghui,

with the binary you provided I was able to reproduce the same problem. However, if I compile it myself (with a slightly older compiler version) it does not appear. I'm currently checking the latest version and try narrow down the problem: I guess it's the combination of Xcode* & compiler that unveils this problem.

While I'm at it: which Xcode* version are you using?

Best regards,

Georg Zitzlsberger

[mattnotting]

Helle Georg, my xcode version is 4.2.1 (4D502). My intel compiler is 12.1.2 and my idb version is 12.1.

Yes. I think the older version of intel fortran compiler doesn't have this problem. I used to use version 10 to compile and debug my programs under suse linux 10.3, and there was never any problems.

Thanks a lot for your help.

Jianghui

[Georg_Z_Intel]

Hello Jianghui,

after updating Xcode to 4.2.1 I'm not seeing the problem with your binary anymore.
To help me reconstruct your system configuration I'd like to ask you for the following:

i) Please extend fout.f90 by the following:

[fortran]program fout
implicit none

real*8,allocatable:: a(:,:)
integer aerr
allocate(a(20,20), stat=aerr)
write(*,*) aerr
call sps(a)
write(*,*) a(1:9,1)
call sps(a)
write(*,*) a(1:9,1)
call sps(a)
write(*,*) a(1:9,1)
call sps(a)
write(*,*) a(1:9,1)

deallocate(a)
stop
end[/fortran]

Print-out of aerr should be 0 with normal execution.

ii) What's the output of:
ifort -w -g -save-temps -fpic fout.f90 sps.f90 -o fout -Wl,-no_pie -#

iii) If you start the debugger and repeat the steps you mentioned, what is the value of aerr (first print-out on console) and what's the result of "print a" (print-out of allocated array). The latter should print correct values and not "".

Thank you very much,

Georg Zitzlsberger

[mattnotting]

Hi Georg,

I've just tried your suggestions. These are my output:

1) Yes. the 'aerr' is 0

2) The output is
