Bug ID: 94336
Summary: template keyword accepted before destructor names
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
We accept the following:
template<typename T> void f(T *p) { p->template ~X(); }
template<typename T> struct X {};
void g(X<int> *p) { f(p); }
but arguably we shouldn't because [temp.names]/5: A name prefixed by the
keyword template shall be a template-id or the name shall refer to a class
template or an alias template.
