The assert will vanish, because you've already done the range check with "offset == (int32_t)offset".
Actually, don't you want offset == sextract64(offset, 0, 34), and use pcaddu18i? Depending on the memory map of qemu, those extra bits could make the difference in directly reaching the main executable.
