Bug ID: 58932 Summary: [4.9 Regression][C++11] Deleted functions and SFINAE in partial template specializations Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: lucdanton at free dot fr Created attachment 31114 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31114&action=edit Testcase Using: $ gcc-snapshot --version gcc-snapshot (Debian 20131021-1) 4.9.0 20131021 (experimental) [trunk revision 203899] with flags -std=c++11 -Wall. The testcase is modified from PR 37208 (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37208). I'm fairly confident that previous 4.9 snapshots used to accept that kind of code (i.e. compile, undefined references notwithstanding), and I think 4.8 does -- no copy of 4.8.2 on hand though.
