Bug ID: 102449
Summary: template parameter with default argument is used
without being verified during explicit specialization
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nickhuang99 at hotmail dot com
Target Milestone: ---
The following snippet code should be rejected because "First" should be checked
with its default argument which is "char"
template<class T,class First=char>
void foo(First,T){}
template<>
void foo<double>(int,double){}
