Bug ID: 70209
Summary: [5 Regression] ICE in strip_typedefs, at
cp/tree.c:1377
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at gcc dot gnu.org
Target Milestone: ---
seen for several packages, fails with the gcc-5-branch on 20160312, not yet
checked with a recent trunk:
class Vector {
public:
typedef float EntryType;
template <typename S1> void m_fn1(S1);
} typedef sfloat_v;
template <typename> struct A {
typedef Vector::EntryType Ta __attribute__((__may_alias__));
Ta *m_data;
void m_fn2(Vector &, Vector &, Vector &, Vector &, Vector &) const;
};
template <>
void A<int>::m_fn2(sfloat_v &, sfloat_v &, sfloat_v &, sfloat_v &,
sfloat_v &p5) const {
p5.m_fn1(m_data)
$ g++ -c foo.ii
foo.ii: In substitution of 'template<class S1> void Vector::m_fn1(S1) [with S1
= <missing>]':
foo.ii:14:16: required from here
foo.ii:14:16: internal compiler error: in strip_typedefs, at cp/tree.c:1377
p5.m_fn1(m_data)
