--- Comment #10 from Nick Desaulniers <ndesaulniers at google dot com> ---
Specifically, it seems this was fixed in the gcc-4.8.2 timeframe. This shows
no issue in gcc-4.8.2, but the issue from comment #5 in gcc-4.8.1. It seems
the Linux kernel works around this with a macro called `asm_volatile_goto` that
simply inserts an empty asm block `asm("");` after an `asm goto`, which even in
this reproducer fixes the problem.
