* malloc/mcheck.c (freehook, reallochook): Handle null pointer args. * hurd/hurdsig.c (_hurd_internal_post_signal): When setting ACT to `ignore, resume the thread if SS_SUSPENDED, regardless of old action. Sun Jun 2 20:14:30 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * locale/programs/linereader.c (lr_open): Don't pass NULL to xstrdup; fix memory leak. (lr_close): Fix memory leak. * hurd/hurdsig.c (_hurd_internal_post_signal): When turning the action Mon Jun 3 01:29:53 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * elf/link.h (struct link_map): Replace l_deps_loaded flag member with `struct link_map **l_searchlist'. * elf/dl-lookup.c (_dl_lookup_symbol): Make SYMBOL_SCOPE arg an array of two link_map ptrs. Search the maps in the l_searchlist of each of the two elts that is non-null. * elf/dl-reloc.c (_dl_relocate_object): Pass proper SCOPE array. * elf/dl-runtime.c: Likewise. * elf/dlsym.c: Likewise. * elf/rtld.c (dl_main): Likewise.
