I'm fairly surprised user emulation works at all for 64-bit targets. I'm fairly sure that code isn't even remotely 64-bit safe. Paul ^ permalink raw reply [flat|nested] 3+ messages in thread

I don't know if this can be guaranteed in every case, but then system calls like exit() don't need any pointers. _________________________________________________________________ Don't just search.
