This problem happening with large modes and not small ones suggests:

1. Maybe the high modes aren't available on the card where you tried
   this and
2. Your program didn't check for failure to get the vid mode and
3. It subsequently wrote to the video device anyways and exploded.

>also : why would malloc cause an invalid page fault???

Probably because the heap management data got scrogged by a bad pointer
write or an array overrun.
