--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
ICE confirmed from 4.8 up to trunk.
Compiling the test with my instrumented gfortran gives
../../work/gcc/fortran/dependency.c:321:11: runtime error: member access within
null pointer of type 'struct gfc_expr'
ASAN:DEADLYSIGNAL
