ID: 52539 Updated by: fel...@php.net Reported by: cataphr...@php.net Summary: Calling function from rebound Closure causes crash -Status: Open +Status: Assigned Type: Bug Package: Scripting Engine problem Operating System: Windows PHP Version: trunk-SVN-2010-08-05 (SVN) -Assigned To: +Assigned To: dmitry Block user comment: N Previous Comments: ------------------------------------------------------------------------ [2010-08-05 09:34:56] cataphr...@php.net Description: ------------ Calling a function in a rebound closure causes a crash. This seems to be caused by dmitry's optimizations because this fixes the issue: #define CACHED_PTR(num) 0. Test script: --------------- class foo { static function getClosure() { return static function () { //causes a crash (fbc not properly defined) in call after rebinding echo get_called_class(), "\n"; }; } } class subFoo { } $c = foo::getClosure(); $c(); //foo $c = $c->bindTo(new subFoo()); $c(); //crash Expected result: ---------------- No crash. Actual result: -------------- > php5ts_debug.dll!zend_do_fcall_common_helper_SPEC(_zend_execute_data * execute_data=0x025d2298, void * * * tsrm_ls=0x02784bf8) Line 302 + 0x3 bytes C php5ts_debug.dll!ZEND_DO_FCALL_SPEC_CONST_HANDLER(_zend_execute_data * execute_data=0x025d2298, void * * * tsrm_ls=0x02784bf8) Line 1721 C php5ts_debug.dll!execute(_zend_op_array * op_array=0x025f23c8, void * * * tsrm_ls=0x02784bf8) Line 136 + 0x11 bytes C php5ts_debug.dll!zend_execute_scripts(int type=8, void * * * tsrm_ls=0x02784bf8, _zval_struct * * retval=0x00000000, int file_count=3, ...)
