            Bug ID: 91784
           Summary: ICE in gfc_real2complex, at fortran/arith.c:2208
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

Follow-up of pr91553, with a negation :


$ cat z1.f90
program p
   complex :: x(1)
   x = (1.0, 2.0) * [real :: -(3.0 + 4.0)]
end


$ cat z2.f90
program p
   complex :: x(1)
   x = (1.0, 2.0) * [real :: -2.0 * (3 + 4)]
end
