            Bug ID: 99717
           Summary: ICE in finish_expr_stmt, at cp/semantics.c:681
           Product: gcc
           Version: 9.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jmullee at yahoo dot com
  Target Milestone: ---

Created attachment 50448
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50448&action=edit
g++ -v, specs, src files, etc

I wasn't able to make it happen again, but the circumstances were:

- using g++ precompiled headers

- incrementally editing an include file, replacing ints with enums (which get
used in a #def macro)

- using CGAL, a header-only library with many templates etc

error:

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Without a testcase, it is going to be hard to reproduce and figure out what was
going on.
