            Bug ID: 107000
           Summary: ICE in gfc_real2complex, at fortran/arith.cc:2243
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

Affects versions down to at least r5 :


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


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