rfree() failed to cope with the case that pg_regcomp() had initialized the regex_t struct but then failed to allocate any memory for re->re_guts (ie, the first malloc call in pg_regcomp() failed). It would try to touch the guts struct anyway, and thus dump core. This is a sufficiently narrow corner case that it's not surprising it's never been seen in the field; but still a bug is a bug, so patch all active branches. Noted while investigating whether we need to call pg_regfree after a failure return from pg_regcomp. Other than this bug, it turns out we don't, so adjust comments appropriately. |
