Bug ID: 91802
Summary: ICE in mio_name_expr_t, at fortran/module.c:2141
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Since gfortran is supporting 15 dimensions :
(up to gcc-7 change sources to use 7+1 dims)
$ cat z0.f90
module m
real :: x(1,2,1,2,1,2,1,2)[1,2,1,2,1,2,1,*]
end
$ gfortran-10-20190915 -c z0.f90 -fcoarray=single
z0.f90:2:44:
2 | real :: x(1,2,1,2,1,2,1,2)[1,2,1,2,1,2,1,*]
| 1
Error: Array specification at (1) has more than 15 dimensions
$ cat z1.f90
module m
real :: x
dimension :: x(1,2,1,2,1,2,1,2)
codimension :: x[1,2,1,2,1,2,1,*]
end
$ gfortran-10-20190915 -c z1.f90 -fcoarray=single
