Pre-emptively update any dirty mirror syntax table before searching src/ChangeLog addition: 2012-09-02 Aidan Kehoe <kehoea@parhasard.net> * regex.c (re_search_2): * regex.c (re_match_2): If the mirror syntax table is dirty, update it before the search, preventing a malloc() inside the search code, something which isn't allowed. Thank you Henry Thompson! tests/ChangeLog addition: 2012-09-02 Aidan Kehoe <kehoea@parhasard.net> * automated/regexp-tests.el: Make sure we can search for character ranges successfully when the syntax table is dirty.
