[PATCH] Fix ____longjmp_chk on x86-64 Linux

Subject: [PATCH] Fix ____longjmp_chk on x86-64 Linux

Hi, the current ____longjmp_chk on x86-64 Linux saves the passed value parameter in %ecx, which is destroyed by the kernel when doing the sigaltstack system call. This patch fixes this by using %ebx instead.

Thanks,
Chung-Lin
