Bug ID: 94771
Summary: g++.dg/concepts/diagnostic10.C fails on mingw
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: sbence92 at gmail dot com
Target Milestone: ---
g++.dg/concepts/diagnostic10.C fails with gcc 10 (ead1c27a530) on mingw target
and host.
Instead of
diagnostic10.C:6:31: error: invalid use of non-static member function 'int
S::f()'
we get
diagnostic10.C:6:31: error: statement cannot resolve address of overloaded
function.
Seems like the fix for Bug 52597 (typeck.c invalid_nonstatic_memfn_p) went with
a special case for -fms-extensions which is a default for mingw.
Compiling with -fno-ms-extensions provides the correct diagnostic.

the commit you mention appears to be unrelated to the test fail, please could
you identify commit the failure started?

The fix for Bug 52597 does seem related, see the change to
invalid_nonstatic_memfn_p in r197131.
I don't know what the MS extension is that requires the t.f syntax to be
allowed. Maybe the extension should be disabled in a requires-expression?

CC Jason to ask why the change does:
+ /* Don't enforce this in MS mode. */
+ if (flag_ms_extensions)
+ return false;

Interesting, the t.f syntax is not allowed anymore even with MSVC:
https://godbolt.org/z/YCK-mv
msvc also doesn't list under extensions_
https://docs.microsoft.com/en-us/cpp/build/reference/microsoft-extensions-to-c-and-cpp?view=vs-2015
and some recent overview on ms extensions:
https://stackoverflow.com/questions/56554567/what-does-the-ms-extensions-flag-do-exactly-with-gcc
Is this a dinosaur that forgot to die?
