Bug ID: 103023
Summary: ICE (Segmentation fault) with !$OMP DECLARE SIMD(func)
linear(ref(u))
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: bartoldeman at users dot sourceforge.net
Target Milestone: ---
Created attachment 51717

Test case for crash
For the following Fortran code gfortran gives a SIGSEGV (tested GCC 9.3,10.3
locally, 11.2 and trunk on Godbolt)
subroutine func(u,ndim)
!$OMP DECLARE SIMD(func) linear(ref(u))
integer, intent(in) :: ndim
double precision, intent(in) :: u(ndim)
end subroutine func
Here's the output for 10.3:
$ gfortran -c -fopenmp-simd openfun2.f90
openfun2.f90:1:15:
1 | subroutine func(u,ndim)
| 1
internal compiler error: Segmentation fault
