Bug ID: 92636
Summary: out-of-class definition of member template of
specialization
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nathan at gcc dot gnu.org
Target Milestone: ---
looks like a long standing bug, and probably already reported. But I ran into
it, it looks well formed [clang accepts it]
template <typename T> class X;
template<>
class X<void>
{
template<typename U> void f (U);
};
template<>
template<typename U>
void X<void>::f (U)
{
}
g++ -c
x.cc:11:6: error: too many template-parameter-lists
11 | void X<void>::f<U> (U)
