I struck a problem while using call_user_function_ex to call a target object method - when that object has a constant defined - and I pass parameters to the callback The call completes successfully if I comment out the constant, or do not pass any parameters. Tried in 7.0.6, 7.0.7, and 7.0.8RC1. Crash occurs in zend_llist_apply_with_argument Test script: --------------- https://github.com/emilkm/aext Expected result: ---------------- PHP code runs a custom extension function, the extension calls back the PHP method successfully passing two parameters. Actual result: -------------- dbg-php-7.0.dll!00007ffbeb3c129f() Unknown dbg-php-7.0.dll!00007ffbeb3c15a5() Unknown dbg-php-7.0.dll!00007ffbeb3c1e2a() Unknown > php7.dll!zend_llist_apply_with_argument(_zend_llist * l, void(*)(void *, void *) func, void * >arg) Line 236 C dbg-php-7.0.dll!00007ffbeb3c37a4() Unknown dbg-php-7.0.dll!00007ffbeb3bc07e() Unknown dbg-php-7.0.dll!00007ffbeb3b8f99() Unknown dbg-php-7.0.dll!00007ffbeb3b916e() Unknown php7.dll!zend_extension_statement_handler(const _zend_extension * extension, _zend_op_array * op_array) Line 1491 C php7.dll!zend_llist_apply_with_argument(_zend_llist * l, void(*)(void *, void *) func, void * arg) Line 236 C php7.dll!ZEND_EXT_STMT_SPEC_HANDLER(_zend_execute_data * execute_data) Line 1301 C php7.dll!execute_ex(_zend_execute_data * ex) Line 417 C dbg-php-7.0.dll!00007ffbeb3b6dce() Unknown php7.dll!ZEND_DO_FCALL_SPEC_HANDLER(_zend_execute_data * execute_data) Line 802 C php7.dll!execute_ex(_zend_execute_data * ex) Line 417 C dbg-php-7.0.dll!00007ffbeb3b6dce() Unknown php7.dll!zend_execute(_zend_op_array * op_array, _zval_struct * return_value) Line 459 C php7.dll!zend_execute_scripts(int type, _zval_struct * retval, int file_count, ...)
