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

[ggrieco9999]

Dear all,
I have a problem with my code that I would you like you help me to understand.
It compiles well, but when I execute it, if the size of the coputation is "large" it gives me the following answer:

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

This is not really surprising. What I find ununderstandable for me is that if I compile with the -traceback options, the compiler tells me that the error happens on a line that opens a file for writing:

open(10,file='../Output_5/R_hr',form='binary',status='unknown')

If I comment this and its related lines, everything works fine. At the beginning I thought it could be a problem of the size or the memory or of the stack but now I do not know.

I tried also to better investigate by means of idb, and the message I receive at the beginning, before of running, is

[1] stopped at [ function main(...) 0x08049483]

I do not know if the two errors are related. Is there anybody who can help me?

Thanks in advance,

Giuseppe

Couldn't you verify whether it is a stack problem by increasing your limit?
Are you asking for suggestions about how to investigate details, how your application might run out of space when allocating buffers for a newly opened file? You aren't at all clear about your question, and you leave us guessing about your software versions.
