* Fix GC_register_disclaim_proc for leak-finding modeIvan Maidanski2018-11-291-2/+6
| | | | | | | | | | | | | | | | | Issue #252 (bdwgc).

| | | | | | | | | | | | | Also, a check is added that the actual finalizer closure pointer does not have FINALIZER_CLOSURE_FLAG set. * fnlz_mlc.c (GC_register_disclaim_proc): Add assertion that proc is non-null. * fnlz_mlc.c (GC_finalized_malloc): Add assertions that fclos argument is non-null and that fclos itself does not have FINALIZER_CLOSURE_FLAG set. * include/gc_disclaim.h (GC_register_disclaim_proc, GC_finalized_malloc): Add GC_ATTR_NONNULL for the pointer argument.
