I've tried the following program to test the malloc crash and I can   
conclude:
It crashes under CWSDPMI but not under Windows 95. I also noticed that   
it's on the moment that a malloc fails (or in the next malloc?) that this   
crash occurs. BTW : I did this test under CWSDPMI Beta 9, not the final   
release (I'll check that later), so maybe there is no problem?

#include <stdlib.h>

void main() {
  int i;
  void *ptr;
  for (i = 0; i < 5000; i++)  {
     ptr = (void *)malloc (10000);
     printf ("%d:%d\n", i, (ptr==NULL));
  }
}
