I would guess that it's some kind of memory-related bug, but I haven't been able to track it down yet.

With my patch all tests succeed. So we definitely need to check processor registers for PMC/Buffers.
If setjmp does save all the registers as i386/gcc does, the setjmp is enough. For other architectures/compilers we need some assembler code, to put all processor registers in Parrot_jump_buff. A look at the sources of gcc/config/* or ruby shows how to do it ;-)
Also instead of set_jmp, we need Parrot_set_jmp, which saves registers.
