Yes, that's why I suspect the bug may still be present: he was only concerned with finding a test case showing it breaking something and was not convinced merely by the presence of the visible symbols that break the ABI. This is part of why I think it may be beneficial to work around broken libgcc.a on musl's side: the breakage is subtle when it happens and it's hard to convince users that there really is a bug. Rich
