Memory problem


Here I am again ! (see my former message VirtualAlloc failed : 26/02/2001 09h21)

I have now installed CygWin 1.1.8 on NT 4.0.

I have a finite element program in c++ which works on SGI. I want it to work on NT.

I compiled this program with cygwin, using the bash and the new library gcc-3 : everything went OK.

With cygnus (I had before : see my former message Virtual Alloc failed), I could run small programs.

Now, I always have a problem of memory. This is the message I have with one of the data file :

      0 [sig] v 270 stackdump: Dumping stack trace to v.exe.stackdump
Aborted (core dumped)

By the way, I cannot find the core file.

This file v.exe.stackdump is the following (I guess it won't help you, but...) :

End of stack trace (more stack frames may be present)

This error always occured at the same moment, during the execution of the program.

The execution requires about 450 Mo on SGI, and the PC has 768 Mo RAM. I don't understand why there is a problem of memory.

Should I change things in my program in order to make it work under NT ? Should I had some options when I run gcc in order to allow the program to use more memory ?

I hope you have an idea of the problem...

Thanks a lot,

Tony LELIEVRE.

This is my cygcheck -r -s -v
