Eric, IRC user ddrown confirmed the x64 patch I mentioned earlier seems to fix the issue on i386 as well. I'm not really sure what to do with that information. Is it possible to patch Leaf with it? https://gist.github.com/ddrown/15e943b8fe1da398320b0c0518c95554
I don't know. It looks like the RESTORE2 macro is extended with a nop operator in this patch. This looks like assembly code.
The thing that puzzles me most is that the current code looks like the following.
#define RESTORE(name, syscall) RESTORE2(name, syscall)
#define RESTORE2(name, syscall) \
__asm__ ( \
"nop\n" \
".text\n" \
"__" #name ":\n" \
" movq $" #syscall ", %rax\n" \
" syscall\n" \
);
So it looks like the patch has already been applied. Very definitely
ddrown has not started from the same codebase, so I would be very
reluctant to follow this path.
