Bug ID: 58510
Summary: [4.9 regression] [c++0x] ICE with multiple non-static
data initializations 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++0x") triggers an ICE
on trunk:
========================
void foo()
{
union
{
int i = 0;
char c = 0;
};
}
========================
bug.cc: In function 'void foo()':
bug.cc:4:3: error: multiple fields in union 'foo()::<anonymous union>'
initialized
{
^
bug.cc: In constructor 'constexpr foo()::<anonymous union>::<constructor>()':
bug.cc:4:3: error: initializations for multiple members of 'foo()::<anonymous
union>'
bug.cc: In function 'void foo()':
bug.cc:7:4: note: synthesized method 'constexpr foo()::<anonymous
union>::<constructor>()' first required here
};
^
