Bug ID: 66103
Summary: [6 Regression] ICE verify_type failed
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
Target Milestone: ---
The following program used to compile awhile ago, but now it ICEs when compiled
with "g++ -flto -g". It works without "-g"
class ios_base {
public:
class Init {
public:
Init ();
};
};
static ios_base::Init __ioinit;
class Foo {
static const Foo m_var;
static inline const Foo & getFoo () {
return m_var;
}
};
