Bug ID: 59269
Summary: [4.9 Regression] ICE with reference in union
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++11") triggers an ICE
on trunk:
===================
union U
{
int& i = 0;
};
void foo()
{
U();
}
===================
bug.cc:3:12: error: 'U::i' may not have reference type 'int&' because it is a
member of a union
int& i = 0;
^
bug.cc:3:12: error: invalid initialization of non-const reference of type
'int&' from an rvalue of type 'int'
bug.cc: In function 'void foo()':
bug.cc:8:5: internal compiler error: in build_value_init_noctor, at
cp/init.c:385
U();
