Bug #80523 [NEW]: bogus parse error on >4GB source code

From: divinity76 at gmail dot com Operating system: PHP version: 7.4.13 Package: Reproducible crash Bug Type: Bug Bug description:bogus parse error on >4GB source code Description: ------------ it appears that PHP crash when trying to parse source code above 4GB in size, notably the code below is not a syntax error if you change it to $imax = (int)((1*1024*1024*1024)/strlen("'hello',")); but if you just change the 1* to 4*, it's suddenly a "syntax error", PS: don't recommend trying this on a system with less than 20GB ram, htop reported over 18GB ram while running.. Test script: --------------- <?php $str='<?php return array('; $imax = (int)((4*1024*1024*1024)/strlen("'hello',")); echo "generating.."; $str.=str_repeat("'hello',",$imax); $str.=");"; echo "generated. writing."; file_put_contents("wtf.php",$str); echo "written. gcing"; unset($str);gc_collect_cycles(); // << dunno if that actually helps echo ". done. including."; require("wtf.php"); Expected result: ---------------- no syntax error Actual result: -------------- root@x2ratma:/temp/fag# time php fag.php generating..generated. writing.written. gcing. done. including.PHP Parse error: syntax error, unexpected ''h' (T_ENCAPSED_AND_WHITESPACE), expecting ')' in /temp/fag/wtf.php on line 1 real 0m24.960s user 0m4.927s sys 0m17.147s root@x2ratma:/temp/fag# -- Edit bug report at https://bugs.php.net/bug.php?id=80523&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80523&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80523&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80523&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80523&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80523&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80523&r=support Expected behavior: https://bugs.php.net/fix.php?id=80523&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80523&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80523&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80523&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80523&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80523&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80523&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80523&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80523&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80523&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80523&r=mysqlcfg
