Using git master 2bf52e7c28e6d48374c3c4314e06e3600d7f668a I get the following
segfault when I try to run the WebGL conformance test:

Program received signal SIGSEGV, Segmentation fault.
swrastPutImage (draw=0xa9c26b00, op=3, x=0, y=0, w=621768704, h=-1249416532, 
    data=0x2c800000 "", loaderPrivate=0xa4ea6ac0) at drisw_glx.c:191
191       ximage->width = w;

I'm not sure if it's the same as bug 33203 (the patch suggested there doesn't
make a difference).

Firefox version is Minefield 4.0b10pre (2011-01-17)
