[CVE-2009-5155] Diagnose ERE '()|\1'submit/tizen_6.0_base/20230622.061909accepted/tizen/6.0/base/tool/20230625.221419accepted/tizen/6.0/base/20230713.143149tizen_6.0_baseaccepted/tizen_6.0_base_toolaccepted/tizen_6.0_base
Problem reported by Hanno B?ck in: http://bugs.gnu.org/21513
* lib/regcomp.c (parse_reg_exp): While parsing alternatives, keep
track of the set of previously-completed subexpressions available
before the first alternative, and restore this set just before
parsing each subsequent alternative. This lets us diagnose the
invalid back-reference in the ERE '()|\1'.
