The problem here is that the JIT generated code is using a two byte encoding for the \
pop %eax instruction (0x83 0xC0) and valgrind is only coping with the more common \
single byte encoding (0x58). It's decoder for the two byte case only knows handles \
pops to memory and asserts if asked to pop to a register.
