Bug ID: 103473
Summary: [11/12 Regression] ICE in simplify_minmaxloc_nodim, at
fortran/simplify.c:5287
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
There seems to be a difference between minloc/maxloc and other intrinsics.
This started recently between 20211031 and 20211107 :
(gcc configured with --enable-checking=yes)
$ cat z1.f90
subroutine s
integer, parameter :: a(+'1') = [1]
print *, minloc(a)
print *, maxloc(a)
end
$ gfortran-12-20211128 -c z1.f90
z1.f90:2:27:
2 | integer, parameter :: a(+'1') = [1]
| 1
Error: Operand of unary numeric operator '+' at (1) is UNKNOWN
z1.f90:2:32:
2 | integer, parameter :: a(+'1') = [1]
| 1
Error: Parameter array 'a' at (1) cannot be automatic or of deferred shape
