Bug #68057 [NEW]: Incorrect parsing of big arrays in PHP 5.6.0

From: vostreltsov at gmail dot com Operating system: Linux PHP version: 5.6.0 Package: Arrays related Bug Type: Bug Bug description:Incorrect parsing of big arrays in PHP 5.6.0 Description: ------------ So in my project I have an auto-generated lexer, it contains a big array. I created a simplified script that reproduces the bug. There are 65538 integers and it looks like something overflows inside PHP. The var_dump call ouputs an array of only the last 2 numbers. Removing last 2 numbers yields an empty array. If I remove last 3 numbers, the output stops at key 32766, that is 32767 values. Test script: --------------- http://filebin.ca/1atoDItGZU2A Expected result: ---------------- All of 65538 integers Actual result: -------------- array(2) { [0]=> int(0) [1]=> int(0) } -- Edit bug report at https://bugs.php.net/bug.php?id=68057&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68057&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68057&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68057&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68057&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68057&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68057&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68057&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68057&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68057&r=support Expected behavior: https://bugs.php.net/fix.php?id=68057&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68057&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68057&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68057&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68057&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68057&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68057&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68057&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68057&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68057&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68057&r=mysqlcfg
