            Bug ID: 115216
           Summary: operator auto() gets instantiatied too eagerly
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

Full example in:

https://godbolt.org/z/3hG5fh1PW

The example can be compiled either by commenting out line 24 or by swapping=
 in
line 8 for line 9. In any case line 25 works. Thus there is a difference
between
the terms "xx[1]" and "xx.operator[](1)".

The error occurs with all recent gcc versions. It doesn't occur with any cl=
ang
version.=
