Bug ID: 58501
Summary: [4.7/4.8/4.9 regression] [c++0x] Crash with
brace-enclosed initializer as default parameter
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 valid code snippet (compiled with "-std=gnu++0x") triggers an ICE
since GCC 4.7.0:
========================
struct A
{
~A();
};
int foo(A = {});
int i = foo();
========================
bug.cc: In function 'void __static_initialization_and_destruction_0(int, int)':
bug.cc:8:13: internal compiler error: in create_tmp_var, at gimplify.c:438
int i = foo();

Before GCC 4.7.0 the code was wrongly rejected.

I don't think this can be classed as a regression when the syntax wasn't
supported until 4.7.0, so never worked

--- Comment #4 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
Fixed by Jason's patch for PR60367.
The testcase added there seems to cover the testcase here, so no further action
is required. Marking as duplicate then.
