re PR c/41935 (ICE : tree check: expected integer_cst, have nop_expr in int_cst_value, at tree.c:8301)
PR middle-end/41935
* c-common.c (fold_offsetof_1) <case ARRAY_REF>: Don't crash for VLAs
or non-constant index, allow index one past the last element and
allow exceeding array bound in arrays that might be used as flexible
array members.
* gcc.dg/pr41935.c: New test.
* c-c++-common/pr41935.c: New test.
* c-c++-common/builtin-offsetof.c (f0): Allow index one past the last
element.
* gcc.c-torture/execute/pr41935.c: New test.
