Well, your own Linux/x86-64 builds do not have this failure, neither normally nor for -m32. Either this bug is invalid, or it is a wrong-code somewhere else. So, no "may"s please. Can you put a breakpoint in warning_at for the empty-body warning, and check what's the value of warn_empty_body? If warn_empty_body is 1, can you check where it is set to 1? It should not be unless -Wempty-body or -Wextra are given. If it is -1, likewise, it should have been set to 0 or 1 in opts.c. If it is 0, can you test the value of "option_enabled (OPT_Wempty_body)"? It should also be 0, or option_enabled is miscompiled. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37683
