Bug ID: 82904
Summary: ICE in make_ssa_name_fn, at tree-ssanames.c:261
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Together with -fcoarray=lib at -Os, -O1 or higher :
$ cat z1.f90
program p
save
character(:), allocatable :: x
character(:), allocatable :: y[:]
allocate (character(3) :: y[*])
allocate (x, source='abc')
y[1] = x
end
$ gfortran-8-20171105 -O2 -c z1.f90 -fcoarray=single
$
$ gfortran-8-20171105 -O2 -c z1.f90 -fcoarray=lib
during IPA pass: inline
z1.f90:8:0:
end
internal compiler error: Segmentation fault
