re PR c/41673 (variable-length array dereference inside sizeof gives "warning: dereferencing type-punned pointer will break strict-aliasing rules")
PR c/41673
* alias.c (get_alias_set): Call langhook before returning 0 for
types with structural equality.
* c-common.c (c_common_get_alias_set): Use alias set of element
type for arrays with structural comparison.
testsuite:
* gcc.dg/Wstrict-aliasing-bogus-vla-1.c: New test.
