Yes, it only works by chance, because the offset passed to lseek is invalid, but the error code is ignored in Pexec. But the emulation fails because it calculates an invalid memory address.

Of course you could easily fix the emulation, by checking the symbol table length either for that specific value (if it is always the same), or for being negative, and ignore it in that case.
