the following, reduced from PR29975, causes a gfortran ICE:
MODULE test
INTEGER, PARAMETER :: dp=KIND(0.0D0), xas_scf_default=1, xas_2s_type=2
TYPE xas_control_type
INTEGER :: state_type,nexc_atoms
END TYPE
TYPE xas_environment_type
INTEGER :: scf_method
END TYPE
CONTAINS
SUBROUTINE xas_env_init(xas_env, xas_control)
TYPE(xas_environment_type), POINTER :: xas_env
TYPE(xas_control_type) :: xas_control
REAL(dp), DIMENSION(:, :), POINTER :: sto_alpha
IF(xas_env%scf_method==xas_scf_default) THEN
ALLOCATE(sto_alpha(1,0:1),STAT=istat)
ELSEIF( xas_control%state_type == xas_2s_type ) THEN
ALLOCATE(sto_alpha(2,0:1),STAT=istat)
END IF
DO iat = 1,xas_control%nexc_atoms
sto_alpha = 0.0_dp
END DO
END SUBROUTINE xas_env_init
END MODULE
gfortran -O2 -ftree-loop-linear test.f90
test.f90: In function ‘xas_env_init’:
test.f90:10: internal compiler error: Segmentation fault
