Just tried to build pixman 0.32.6 on my playstation3 and it passes
tests without problems.

Can you provide more details about your compiler? Also is it a 32-bit
system?

Does reducing the level of optimizations help? This can be done by
setting the CFLAGS environment variable to "-O1" or even to "-O0"
before running the configure script.

Does disabling Altivec help? This can be done by setting
the PIXMAN_DISABLE environment variable to "vmx".

Are you sure that the newly built pixman library is used for tests
and not some older installed version. You can try to run pixman
configure with an extra "--disable-shared" option and check if
this affects anything.

By trying these steps, we can get more information about the problem
and find a possible solution.
