            Bug ID: 94984
           Summary: rejects requires clause in array declaration
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nathan at gcc dot gnu.org
  Target Milestone: ---

Daveed tells us we reject this (clang & edg accept).  gcc-9 and 10 reject it
(so not a regression)

template<int N>
char (*f(int i))[N] requires(sizeof(i) < 100) {}

dav.ii:2:21: error: expected initializer before 'requires'
    2 | char (*f(int i))[N] requires(sizeof(i) < 100) {}

--- Comment #1 from Nathan Sidwell <nathan at gcc dot gnu.org> ---
silly write only comments: 

Daveed tried the following, which we accept


template<int N>
char (*f(int i) requires(sizeof(i) < 100))[N] {}

(note how the trailing-requires-clause was moved to within the declarator) and
sure enough GCC accepts that.
