            Bug ID: 97994
           Summary: [11 Regression] ICE in nothrow_spec_p, at
                    cp/except.c:1183
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

Changed between 20200621 and 20200628 :


$ cat z1.cc
struct S;
template <class T> void foo () noexcept (T::v);
template <class ...A>
void bar (void (A...) noexcept)
{ bar (foo<S>); }


$ g++-11-20200621 -c z1.cc
$
$ g++-11-20201122 -c z1.cc
z1.cc: In substitution of 'template<class ... A> void bar(void (*)(A ...)
noexcept) [with A = <missing>]':
z1.cc:5:14:   required from here
z1.cc:5:14: internal compiler error: in nothrow_spec_p, at cp/except.c:1183
    5 | { bar (foo<S>); }
