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.

EDG also accepts it, and clang 9.0.1 segfaults! clang 11 rejects it:
d.cc:1:50: error: unknown type name 'X'
template<typename T> void f(T *p) { p->template ~X(); }

c++: template keyword accepted before destructor names [PR94336]
This came up on the C++ core list recently. We don't diagnose the case
when 'template' is followed by a destructor name which is not permitted
by [temp.names]/5.
PR c++/94336 - template keyword accepted before destructor names.
* parser.c (cp_parser_unqualified_id): Give an error when
'template'
is followed by a destructor name.
* g++.dg/template/template-keyword2.C: New test.
