Bug #51967 [NEW]: iconv_mime_encode() eats all memory

From: Operating system: linux PHP version: 5.2.13 Package: *Mail Related Bug Type: Bug Bug description:iconv_mime_encode() eats all memory Description: ------------ We got this error: PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 2194780439 bytes) in After examining the reason, I found this test to reproduce it. Because we don't have 5.2.13 in production, this is only tested with 5.2.12, but as far as I know, there was no change here, since that, so it should also be reproduce able with 5.2.13. Test script: --------------- <?php $string = 'Короткое замыкание в цепи датчика емкостного водонагревателя'; error_log(phpversion()); error_log ("1"); error_log (iconv_mime_encode( 'Subject', $string, array( 'scheme' => 'Q', 'input-charset' => 'utf-8', 'output-charset' => 'utf-8', 'line-length' => 74, 'linke-break-chars' => "\r\n") )); error_log("2"); Actual result: -------------- The script prints out only "1" and breaks down with the fatal error. Take care! It eats all memory if no limits are here! -- Edit bug report at http://bugs.php.net/bug.php?id=51967&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51967&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51967&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=51967&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=51967&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51967&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51967&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51967&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51967&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51967&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51967&r=support Expected behavior: http://bugs.php.net/fix.php?id=51967&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51967&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51967&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51967&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51967&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51967&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51967&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51967&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51967&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51967&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51967&r=mysqlcfg
