           Summary: [C++0X] ICE when using constexpr with
                    -fno-elide-constructors
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: gcc-bugzi...@contacts.eelis.net


Compiling

  struct S { bool b; };
  constexpr S f() { return S{true}; }
  static_assert(f().b,  "");

with

  g++ -std=c++0x -fno-elide-constructors

results in

  t.cpp:3:26: internal compiler error: Segmentation fault
  Please submit a full bug report,
  with preprocessed source if appropriate.
  See <http://gcc.gnu.org/bugs.html> for instructions.

Omitting -fno-elide-constructors makes the problem go away.

I'm using GCC svn r166710.
