Thread local storage is when a C variable is marked with "__thread" as
being local to a thread. Pixman has an internal cache that relies on
this mechanism working. On compilers/systems where thread local storage
doesn't work, you'll get the above message.

Since you are using a Beta compiler, broken thread local support is
definitely my first suspicion. One thing you might try is changing 

    #define N_CACHED_FAST_PATHS 8

to

    #define N_CACHED_FAST_PATHS 0

in pixman-implementation.c. That probably will fix the issue at a
potentially significant loss of performance.
