Bug #69693 [NEW]: Reproducible Corruption on Variables

From: bugs at tmarques dot com Operating system: Linux x32 PHP version: 5.5.25 Package: *General Issues Bug Type: Bug Bug description:Reproducible Corruption on Variables Description: ------------ This is a bug I ran into when using Wordpress normally. After running a script for a while on a x32 ABI php, it enters an infinite loop that exhausts process memory. Upon investigation, two variables that have integers get summed and return a float. Depending on the input text, the loop doesn't trigger the bug. This doesn't happen on i386/i686, haven't tested on x86-64. Test script: --------------- Please see both examples at: https://gist.github.com/anonymous/4320f460cd1e4144df2a Relevant code is "run.php" from lines 96 to 120. It never triggers if I copy the $text variable to another one that's not even used ($_test). It also returns the correct sum for a test in the code as: if ( is_float( $i + $l ) === TRUE ) So I have to sum and check if the value is big (it usually returns some float of E+18 magnitude). Expected result: ---------------- Integer variables sum and result in an integer. Actual result: -------------- Sum of two integers returns a float. -- Edit bug report at https://bugs.php.net/bug.php?id=69693&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69693&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69693&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69693&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69693&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69693&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69693&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69693&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69693&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69693&r=support Expected behavior: https://bugs.php.net/fix.php?id=69693&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69693&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69693&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69693&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69693&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69693&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69693&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69693&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69693&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69693&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69693&r=mysqlcfg
