That's not there, (but my pc's a good 18 months old
VIA/AMD).

Nope, no exec-shield

Will do, i've also tried playing with the vm settings
which didn't help. 'swappiness, overcommit_memory,
overcommit_ratio, max_map_count and min_free_kbytes
'

I've tried doing...
int i;
int j;
char* data;
for(i =0 ; i< 10 ; i++){
 data = HeapAlloc(GetProcessHeap(),0,64*1024*1024);

/*write to the data for linux really allocates it*/
 for(j = 0 ; j < 128; j++){
   data[j*1024*512] = 1;
 }

}
and that works ok.

Well, there's plenty free, and other apps can allocate
memory just fine.

I can possibly look at putting some  pooling code into
DirectX to help reduce fragmentation on that side
(though there's not a lot of memory allocated, and
it's mostly in the same sized blocks), or something in
malloc so that it reports the exact failure.

Oh, I also have an ATI graphics card.
