Hi,

I'm having a few problems with disabling virtual memory under DJGPP.
Should I load cwsdpmi with "-s-", or use cwsdpr0 or set the flag in
crt0.h. Does the latter method sometimes fail? 

Anyway under dos 6.22 with emm386 (possibly even without emm386)
The following simple program fails if you run it a few times on an
amd 586x133 with 20 mb.The keyboard is locked on exit.


#include <stdio.h>
#include some other basic .h files

char large_array[1024*1024*4];

void main(void)
{

  system("mem /c /p");  // even a simple puts() here causes a crash sometimes

}


The size of the array seems to make little difference, Neither does increase-
ing the stack size help much.I'm really at a loss.Any help would be much
appreciated.
