DEREFERENCING UT_DBG_NULL_PTR The abort() call is standard C but InnoDB only uses it in GCC environments. UT_DBG_USE_ABORT is not defined the code crashed by dereferencing a null pointer instead of calling abort(). Other code throughout MySQL including ndb, sql, mysys and other places call abort() directly. This bug also affects innodb.innodb_bug14147491.test which fails randomly on windows because of this issue. Approved by marko in http://rb.no.oracle.com/rb/r/1936/
