SIGSEV, segmentation fault occured

[askar]

I post this message again because i didn't find any solutions to this problem and i hope thatsomeone can help me out.

Hi all,

i have exactly the same problem described by xiongye. I have also made the same link and when i am trying to run my program i get the same error message :

forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image PC Routine Line Source
dvs75 006088B7 Unknown Unknown Unknown
dvs75 0826D970 Unknown Unknown Unknown
dvs75 5453454E Unknown Unknown Unknown

Stack trace terminated abnormally.

I have unlimited stack size and i have checked the code in an alpha workstation and in my pc compiled with the compaq compiler and the code runs perfect.In the system with the ifc compiler i used-openmp option. Do you believe that this produces theerror?Any help is appreciated.

Thanks

Andreas

I installed intel fortran 8.0 in Fedora Linux and ran one program called siesta. I met the similar error (with unlimited stacksize):

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

Stack trace terminated abnormally.

And sometimes, it just stops without giving any error explictly. If I strace it, it will give this in the end of strace output:

Hi!

Check if you read from some files and in the do loop (if you do so) you are more steps than data available in the files.

I received the same type of error when reading from some files where I had fewer recordings than the number of iteration the do loop had expected to read.

Also check if all the things that you read from files are the type that you expect to be... there may be strange characters...
