I think I triggered a bug somewhere in the GC-code but I failed to
find it. When doing several PIO_printf calls parrot segfaults in
get_free_buffer. Strange enough only about 80 calls are necessary to
segfault, but 5000 generations of life.pbc run correct.

Attached is test (patch to t/src/sprintf.t) and a backtrace of the
segfault.
