* elf/dl-close.c: Include stddef.h.
(_dl_close): If called recursively, just remember GC needs to be rerun and decrease l_direct_opencount. Avoid GC if l_direct_opencount decreased to 1. Rerun GC at the end if any destructor unloaded some additional libraries. * elf/Makefile: Add rules to build and run unload6 test. * elf/unload6.c: New test. * elf/unload6mod1.c: New file. * elf/unload6mod2.c: New file. * elf/unload6mod3.c: New file. * malloc/hooks.c (mem2chunk_check): Add magic_p argument, set *magic_p if magic_p is not NULL. (top_check): Invoke MALLOC_FAILURE_ACTION if MORECORE failed. (malloc_check): Fail if sz == -1. (free_check): Adjust mem2chunk_check caller. (realloc_check): Likewise. Fail if bytes == -1. If bytes == 0 and oldmem != NULL, call free_check and return NULL. If reallocating and returning NULL, invert magic byte again to make oldmem valid region for further checking. (memalign_check): Fail if bytes == -1. * malloc/Makefile: Add rules to build and run tst-mcheck. * malloc/tst-mcheck.c: New test.
