However, in 7.4 EX(opline) is no longer initialized at all (until a SAVE_OPLINE in a throwing opcode), which means that we may crash when trying to fetch the current line number on OOM. I think that we should bring back EX(opline) initialization in init_func_execute_data. @dmitry: Do you see any other way? ------------------------------------------------------------------------ [2020-01-10 11:56:38] vinayrachapalli7 at gmail dot com Description: ------------ It crashes when we run the following script on PHP 7.4, but in 7.3, it'll through error like Fatal error: Allowed memory size of 134217728 bytes exhausted at ...
