Free loop variables If the generator is closed before it has finished running, it may happen that some FREE or SWITCH_FREE opcodes haven't been executed and memory is leaked. This fixes it by walking the brk_cont_array and manually freeing the variables. 2012-05-27 15:14:20 +00:00			`--TEST--`

Remove asterix modifier (*) for generators Generators are now automatically detected by the presence of a `yield` expression in their body. This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead additional checks for ZEND_ACC_GENERATOR are added to the fcall_common helper and zend_call_function. This also adds a new function zend_generator_create_zval, which handles the actual creation of the generator zval from an op array. I feel like I should deglobalize the zend_create_execute_data_from_op_array code a bit. It currently changes EG(current_execute_data) and EG(opline_ptr) which is somewhat confusing (given the name). 2012-07-19 22:49:50 +00:00			`function gen(array $array) {`
