Bug ID: 93338
Summary: [8/9/10 Regression] ICE in make_ssa_name_fn, at
tree-ssanames.c:282
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Started with gfortran-8 (before 20180525) at -O[123] :
(gfortran-7 compiles it)
$ cat z1.f90
program p
type t
character(:), allocatable :: a(:)
end type
type(t), allocatable, target :: x
x = t(['abc'])
associate (y => x%a(:))
if ( any(y /= 'abc') ) stop
end associate
end
$ gfortran-7 -c z1.f90 -O2
$ gfortran-10-20200119 -c z1.f90 -O0
