* lib/regex_internal.c (re_string_reconstruct): Don't assume buffer lengths fit in regoff_t; this isn't true if regoff_t is the same width as size_t. * lib/regex.c (re_search_internal): 5th arg is LAST_START (= START + RANGE) instead of RANGE. This avoids overflow problems when regoff_t is the same width as size_t. All callers changed. (re_search_2_stub): Check for overflow when adding the sizes of the two strings. (re_search_stub): Check for overflow when adding START to RANGE; if it occurs, substitute the extreme value. * config/srclist.txt: Add glibc bug 1284.
