Segmentation fault (SIGSEGV)

[tvigneshbabu]

Sir / Mam,
I am Dr.D.Sasireka, Physics Teacher in India, I have taking practice in
Fortran90 & LmtART. Now I am trying my Program in my laptop (Centrino Duo Processor / 1 GB RAM) by downloading Intel Fortran Compiler 10.1.018 (IA32 / Intel 64) from your site. (for non-commercial use)
When Compilation there is no error occurs, but during the running of program I had facing Segmentation fault as follows,
forrt1: severe (174): SIGSEGV, segmentation fault occured
ImagePcRoutineLineSOurce
main.exe082873E5---------unknown----------------------

main.exe081F8BD2---------unknown----------------------
libc.so.600795E23---------unknown----------------------
main.exe0804A2A1---------unknown----------------------
kindly help me.

Thanks & Regards,
Dr.D.Sasireka

Dr. Sasireka,

Welcome to the forum.

There are many possible reasons for this error. Please add the following switches to the compile and this will provide some more information:

-CB -traceback -gen-interface -warn interface

then run the program again. If you get different error messages, post them here.

Also, please do not post serial numbers in this forum. I removed it from your post.

Dear Mr Lionel,

I apologize for replying so late to your post but I currently encounter the same problem as Dr. Sasireka. I am a PhD student trying to use the same code (LmtART).
After compiling without problems (except : LOOP WAS VECTORIZED), I got the following error message when I launch the program :

forrtl: severe (174): SIGSEGV, segmentation fault occurred

(lmtart is my .exe)

Do you know if Dr. Sasireka finally solved this problem ? Because I cannot see other posts after yours.

I also tried the switches you proposed. I so get following errors during compiling :

fortcom: Error: bnd_eigen1c.f, line 424: If the actual argument is scalar, the corresponding dummy argument shall be scalar unless the actual argument is an element of an array that is not an assumed-shape or pointer array, or a substring of such an element. [DX]

Is there a problem in the code ? Because according to its author, it was successfully tested on
IBM AIX XLF
WIN95/98/NT/00 Digital Visual Fortran VI
WIN95/98/NT/00 Miscrosoft Fortran Power Station
DEC Alpha
SUN
PGF LINUX
So I assumed I am doing something wrong, but I do not understand what.

So if you think you could help me, thanks !

Best regards,

Vincent

I'll reply in the thread you started.

Dear Dr.Sasireka/Mr. Steve Lionel,

I'm new to LMTO method, I'm trying to install lmtart using what are the basic command should i use to compile lmtart andd where to find the compiler in suse linux 11.2

I appreciate any reply and be grateful for the same

OpenSUSE 11.2 is not officially supported, but do read these instructions:

[ndsr]

Thank you Mr. Ronald W.Green. I would also like to know if Open Suse 10.3 is supported or not?

[Ron_Green]

OpenSUSE 10.3 is not officially supported. In fact, this is the first I have heard of this version. I will test it and update my document.

Although we may not officially support these new versions, we do try to adapt quickly and test them with our compilers. It is difficult to keep up, as it takes us time to set up servers, rewrite our testing scripts (if needed), etc. Thus, it is safest to use Linux distributions and versions that are well established - ie about 1.5 years old.

As soon as new distributions come out, we find from users very quickly if there are bugs, and of course, we try to adapt and fix the compiler. However OFFICIAL support usually lags by a year or more.

OpenSuSE 10.3 is relatively old (in your recommended age bracket); I used to use it successfully with earlier versions of Intel compilers, with the exception of not being able to make 32-bit icc and ifort work together on x86_64. All OpenSuSE versions I've seen are fairly straightforward, once you get used to opening up YaST and installing libstdc++-33 (both 32- and 64-bit).

[Ron_Green]

My mistake, for some reason my mind read "11.3" and I paniced thinking there was yet another new Linux distro that I'd need to test.
