re PR fortran/32594 (substring simplification leads to ICE)
PR fortran/32594
* trans-expr.c (gfc_conv_substring_expr): Only call
gfc_conv_substring if expr->ref is not NULL.
* expr.c (gfc_is_constant_expr): If e->ref is NULL, the substring
expression might be a constant.
(gfc_simplify_expr): Handle missing start and end, as well as
missing ref.
* gfortran.dg/substr_5.f90: New test.
