--- Comment #12 from Pedro Alves <palves at redhat dot com> --- TBC, the reason I filed this, is because GDB had an incorrect use like that that survived for a few months: https://sourceware.org/ml/gdb-patches/2016-11/msg00933.html until someone compiled GDB with clang: https://sourceware.org/bugzilla/show_bug.cgi?id=21206#c6 I can only imagine how many more incorrect uses are out there.
