FAIL: 28_regex/traits/wchar_t/isctype.cc execution test (same fail message still at r219089). Committer of libstdc++ changes in the indicated revision range CC:ed. Unexpectedly, I don't see this for other non-linux and/or "newlib" targets with libstdc++ results posted to gcc-testresults@. There was also a commit to gcc/ifcvt.c in this range, I'll triage the revision range to exclude that.
