The situation appears to be more complicated than I thought initially. I've did
additional debugging and now think that all games are suffering from the same
bug in a driver - the symptoms are quite similar. However, there are many ways
to "activate" this bug, so every game (or GL app in general) has it's own
workaround. For instance, in Trigger you should avoid GL_LINEAR_MIPMAP_LINEAR,
in Torcs you should disable GL_ALPHA_TEST when rendering multitextures (it is
always connected with textures somehow) and so on. Usually, the program hangs
between return statement and the next line of code, i.e. in the sample code
below:
int some_func() {
...
printf("BEFORE\n");
return 1;
}
...
while (some_func) {
printf("AFTER\n");
}
you will see "BEFORE" line but not "AFTER".
So, I've prepared a very simple demo program (see attachement) below which hangs
my computer. Hope it will help debugging driver. More details are in attachment
comments.
