[BZ #3155]
2006-09-07 Jakub Jelinek <jakub@redhat.com> [BZ #3155] * sysdeps/powerpc/powerpc32/fpu/s_lrint.S (__lrint): Don't access stack below r1. * posix/regex_internal.c (re_string_reconstruct): Handle offset < pstr->valid_raw_len && pstr->offsets_needed case. Ensure no bytes read before raw_mbs array. Pass a saved copy of pstr->valid_len - 1 rather than pstr->valid_raw_len - 1 to re_string_context_at. * posix/Makefile: Add rules to build and run bug-regex26 test. * posix/bug-regex26.c: New test. * dlfcn/Makefile (LDLIBS-bug-atexit3-lib.so): Add ld.so.
