Bus Error

scroto — Sat, 21 Jan 2006 01:44:05 GMT

Hi,

Im quite new to the intel fortran compiler, but have managed to install and configure it. It also compiles a program that i have written, but when this program is run it displays 'Bus Error' and the program exits. This program runs fine on other machines so I have the feeling there is something wrong with either my machine or the install of the compiler. Any help with this problem would be much appreciated.

I am running SuSE-Linux 10 x86_64, on an AMD Atholon 3800+ if this is any help.

I have not received this error on linux, but a "bus error" on an older version of HP-UXwas traced to a mismatch in the number of arguments between a call and a subroutine. This was before the advent of optional arguments in Fortran.

After further testing of the program I have found it also gives an error of :

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

and the program needs to be killed for it to terminate. It also only gives these errors if the arrays in the program are large eg greater than 60 elements in 1 dimension. If they are less the program works fine.

Did you try compiling and running with options such as -C -traceback, to attempt to catch subscript range errors and the like?

As I said in an earlier post im am pretty new to the intel compiler so i don't really know what im looking for but the error i got with the -C option is :

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

and the error given with -traceback is :

I had a look at line 58 in the program but it is only a WRITE(6,*)'' command. I don't know if these are at all helpfully. If there is a log the compiler makes which would be useful could you please tell me where it is located.

At this point I suggest you contact Intel Premier Support and attach a test case that reproduces the problem.
