I do not know if I mentioned that in both PC's I have 256MB of physical RAM.
I jsut checked the setting on Win2K for virtual memory and it is set to use
between 384MB and 768MB. Currently it is using 384MB for all drives.

Dug out the original email to save time in back tracking what I did.

I modified make's main.c and added the following line, but the crash still
occured and I couldn't see any extra debug info or extra info in the crash
outout attached below. I also just added a printf after I set the
malloc_debug level so I can see how many time make is called re-cursively.
This was added at line number 774 in make's main.c befiore the main function
along with a #inlcude <crt0.h>.

int _crt0_startup_flags =  _CRT0_FLAG_UNIX_SBRK;

This is the output with the crto startup flag set as above and the maloc
debug level set to 4. Yet a different crash position.  Have I set the crt0
startup flag correctly?

DJGPP_204 D:\dj204\gnu\make-3.791>symify make.exe

Any other suggestions guys?

Is it work migrating from the DJGPP CVS tarball from 15th July to the 29th
July when it is released? Bear in mind I have allready applied the
_open/_create and NTVDM patches.
