Bug #: 56241
Summary: ICE in toplev.c:332 on invalid
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]

This is a result of test reduction gone bad. The test is invalid, but shouldn't
crash the compiler.

constexpr pair (const) :
};
template < 0 >
make_pair () {
}
pair prefix[] = { 0, make_pair }
