I've attached a simple sample of usage for glDrawPixels.  Without seeing 
the actual failing code I can't be sure what's going wrong, but the 
likely cause is failing to set up the pixel transfer mode (which can 
result in trying to read more data than is allowed, causing a protection 
fault).

HTH,
