From: "robert at ocallahan dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/94844] New: Simple nonsensical program accepted by g++ (rejected by clang++) Date: Wed, 29 Apr 2020 09:07:10 +0000 [thread overview] Message-ID: <bug-94844-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94844 Bug ID: 94844 Summary: Simple nonsensical program accepted by g++ (rejected by clang++) Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: robert at ocallahan dot org Target Milestone: --- Testcase: #include <stdio.h> template <typename T> void func(T s) { if (s < 0) { puts("WHAT"); } } typedef long unsigned Foo; int main(void) { func<long Foo>(-1); } g++ (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2): compiles it and generates code that prints "WHAT". clang version 9.0.1 (Fedora 9.0.1-2.fc31): rejects it: /home/roc/tmp/test.cc:9:13: error: type-id cannot have a name func<long Foo>(-1); ^~~ clang++ looks right to me. It doesn't seem right to allow 'unsigned' to modify 'Foo' here. Doing that in a variable declaration is rejected.
