Summary: Internal compiler error with union member
initialization using default constructor
Classification: Unclassified

Version: 4.8.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: tobias.anderberg@gmail.com
class Foo {
public:
private:
static const int kRows = 4;
static const int kCols = 4;
union {
float m_n[kRows][kCols];
float m_m[kRows * kCols] = {
1.0f, 0.0f, 0.0f, 0.0f,
0.0f, 1.0f, 0.0f, 0.0f,
0.0f, 0.0f, 1.0f, 0.0f,
0.0f, 0.0f, 0.0f, 1.0f
};
};
};
int main()
{
Foo myFoo;
return 0;
}
Compile: g++ -std=c++11 foo.cc
Result:
foo.cc: In constructor ‘constexpr Foo::Foo()’:
foo.cc:1:7: internal compiler error: in cx_check_missing_mem_inits, at
cp/semantics.c:6166
class Foo {
^
foo.cc:1:7: internal compiler error: Abort trap: 6

Additional notes:
By either naming the union, or supplying a default constructor the sample
compiles.
