            Bug ID: 61445
           Summary: [C++11][4.10 Regression] ice in instantiate_decl
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

This appears to be a recent regression in trunk.
Source reduced from llvm/tools/clang/tools/clang-check/ClangCheck.cpp

Using trunk @r211286:

int*)::A::m_fn1() [with FactoryT = int]’:

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.

The crash does not reproduce without -std=c++11, nor using trunk build
@r210629.
