--- Comment #12 from Paolo Carlini <paolo.carlini at oracle dot com> ---
The fix caused a regression:
FAIL: g++.dg/template/cond2.C -std=gnu++98 (test for warnings, line 9)
FAIL: g++.dg/template/cond2.C -std=gnu++11 (test for warnings, line 9)
as described here too: http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00425.html
I'm a bit worried, because normally we don't check in the testsuite that those
messages about the instantiation point have the right line number, thus, we may
well have a pretty serious diagnostic regression, beyond the specific failure.
