This is due to a change in the way gcc compiles code ... 3.4.0 may work,
but later versions will cause functions to return prematurely (due to the way
qemu handles translated blocks). I suggested that a fix for this would be to
use function pointer calls instead of directly chaining machine code, but
apparently this is too slow to make qemu usable.
