Bug ID: 93810
Summary: missing -Wmismatched-tags on a typedef of an implicit
class template specialization
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
The typedef below should be diagnosed by -Wmismatched-tags but isn't. Both
Clang and Visual C++ diagnose it as expected.
$ cat t.C && gcc -S -Wmismatched-tags -Wredundant-tags t.C
template <int> class C { };
typedef struct C<0> C0; // missing -Wmismatched-tags
