            Bug ID: 107215
           Summary: ICE in gfc_real2real and gfc_complex2complex
           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: ---

Additional examples affect versions down to at least r5 :


$ cat z1.f90
program p
  double precision, parameter :: z = 1.0d0
  real :: y(1)
  complex :: x(1)
  x = [real :: -'1'] * z
  y = z * [real :: -'1']
  x = [real :: -(.true.)] * z
  y = z * [real :: -(.true.)]
end


$ cat z2.f90
program p
  double precision, parameter :: z = 1.0d0
  real :: y(1)
  complex :: x(1)
  x = [complex :: -'1'] * z
  y = z * [complex :: -'1']
  x = [complex :: -(.true.)] * z
  y = z * [complex :: -(.true.)]
end
