Dear,

I ran stress-test under fuzzing and I found a crash.

I'm not really comfortable with pixman so I don't really know how to report
you the problem.

Please find enclosed modifications I needed to apply to allow fuzzing with
afl.
I disabled HAVE_GCC_VECTOR_EXTENSIONS and adapt smallprng_rand_r to read
from buffer instead of random data based on seed.

To make the stress-test crashes, run ./stress-test rasterize_edges_8.crash

I hope it's not my patch that make pixman crashes.

Please, tell me if you need further information or if I did something wrong.

Best regards,

Vincent LE GARREC
