------- Comment #30 from matz at gcc dot gnu dot org 2010-02-01 12:24 ------- See comment #3 for how (newer) GCC does warn at line 15. Not with the default options, though, but this has good reasons (too many false positives).
You are right that we should be able to improve our diagnostics in this case, as, as you say, line 15 and 22 together create a definitely fishy situation. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42907
