[Libunwind-devel] is_signal_frame not working

[Arne de Bruijn]

Hello,

On my linux 2.6.24 x86_64 kernel with x86 userland the is_signal_frame 
function is not working for SA_SIGINFO signals (always returns 0). This is 
because after the sigreturn syscall there is a 00-byte instead of a 
nop-instruction as the code expects.

The attached patch fixes this problem (and corrects a comment typo).
