Bug #: 56238
Summary: [4.8 regression] ICE in tree check: expected
record_type or union_type or qual_union_type, have
template_type_parm in lookup_conversions, at
cp/search.c:2515
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
Test case:
class A
{
template < typename T > T& get ();
template < typename T > class B
{
void RemovePoint (A& value)
{
static_cast < double >(value.get < T > ());
}
};
};
Compiles fine with 4.7.x, with 4.8 without -std=c++11.
ICE's with -std=c++11 using
g++ (GCC) 4.8.0 20130205 (experimental)
g++ -c t.ii -std=c++11
t.ii: In member function ‘void A::B<T>::RemovePoint(A&)’:
t.ii:8:55: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have template_type_parm in lookup_conversions,
at cp/search.c:2515
static_cast < double >(value.get < T > ());
