Bug ID: 58651
Summary: [4.7/4.8/4.9 Regression] ICE with invalid initializer
list
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=11") triggers an ICE
since GCC 4.4.1:
==============================
struct A
{
int i;
A(int j) : i{{j}} {}
};
A a(0);
==============================
bug.cc: In constructor 'A::A(int)':
bug.cc:4:19: internal compiler error: in gimplify_init_constructor, at
gimplify.c:4236
A(int j) : i{{j}} {}
