What the subject says <g> It bombs back to the desktop with a 'malloc
failure for 1048629' error message.

System specs:
Sempron 3300+
1Gb RAM
NVidia Geforce 6200 w/Forceware 81.98 (IIRC)
WinXP w/SP1 (SP2 caused problems last time I tried it)
DirectX 9.0c

Any ideas? This is what the console shows:
