Xinchen Hui c6037bd3af Fixed bug #70012 (Exception lost with nested finally block) 2015-07-08 17:15:09 +08:00
Dmitry Stogov 5ee8413259 Fixed bug #62210 (Exceptions can leak temporary variables. As a part of the fix serious refactoring was done. op_array->brk_cont_array was removed, and replaced with more general and speed efficient op_array->T_liveliness. ZEND_GOTO opcode is always replaced by ZEND_JMP at compile time). (Bob, Dmitry, Laruence)
