Bug ID: 67311
Summary: ICE calling subroutine with derived type as argument
within OpenMP parallel region
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: acreman at astro dot ex.ac.uk
Target Milestone: ---
The following test case produces an internal compiler error with recent
gfortran versions:
! == Begin test case ==
subroutine test
call openmp_sub
end subroutine test
subroutine openmp_sub
implicit none
TYPE myType
TYPE(myType), DIMENSION(:), POINTER :: x
END TYPE myType
type(myType) :: argument
!$OMP PARALLEL DEFAULT(NONE) PRIVATE(argument)
call foo(argument)
!$OMP END PARALLEL
end subroutine openmp_sub
! == End test case ==
The command line used to build was: gfortran -c -fopenmp test.f90
I see an ICE at versions 4.9.3 and 5.2 on SLES and gfortran 4.9.2 on Mac OS.
The test case compiles OK with version 4.6.3 (SLES) and 4.8.2 (Ubuntu)
The output from gfortran 4.9.3 is:
> gfortran -c -fopenmp test.f90
gfortran: internal compiler error: Segmentation fault (program f951)
