            Bug ID: 60054
           Summary: [c++1y] ICE with auto* cast
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet (compiled with "-std=c++1y") triggers an
ICE on trunk:

==================================
template<typename T> T foo(T);

void bar()
{
  foo((auto*)0);
}
==================================

cc1plus: internal compiler error: Segmentation fault
0xba9c8f crash_signal

0x68c4ae cp_write_global_declarations()
        ../../gcc/gcc/cp/decl2.c:4449
Please submit a full bug report, [etc.]

With a slightly modified example I get a different stack trace:

===========================================
template<typename T> decltype(T{}) foo(T);

void bar()
{
  foo((auto*)0);
}
===========================================

bug.cc: In function 'void bar()':

--- Comment #1 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
The testcases don't fail anymore since 2014-03-08.
Jason, I suspect that this is due to your changes on the day before.
Do you want to add these testcases to the testsuite?
