Bug ID: 80768
Summary: NULL pointer dereferenced in gfc_check_num_images at
fortran/check.c
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: zeccav at gmail dot com
Target Milestone: ---
! NULL pointer dereferenced in gfc_check_num_images at fortran/check.c:5150
! gfortran 8.0.0 trunk 247930
! Target: x86_64-pc-linux-gnu
! must be compiled with option -fcoarray=single
! check.c:5150 if (!gfc_notify_std (GFC_STD_F2008_TS, "FAILED= argument to
NUM_IMAGES at %L", &distance->where))
! pointer "distance" is NULL
! double checked with "gcc_assert(distance);" that fails producing the ICE
!
k5 = num_images(failed=.false.)
end
