From: Operating system: Mac OS X 10.7.1 PHP version: 5.3.8 Package: Reproducible crash Bug Type: Bug Bug description:SplFixedArray::fromArray causing segmentation fault 11
Description: ------------ I created a script that uses SplFileObject to iterate over a CSV file. As it goes, it creates a new object with each line's data and adds the object to an array. Running it with 10k or more lines crashes with a "Segmentation fault: 11" error message, while anything up to 9,999 lines works well. Adjusting PHP's memory limit had no effect. I've attached a partial reduction to this bug. It seems like I really need the elements of the SplFileObject and the class for each line, as skipping either one of those (even when the resulting array is much larger than 10k items) causes the failure to disappear. I'm not sure exactly what the trigger is, however. My reduction includes a sample CSV file of just over 10k lines, and though it still uses SplFileObject and a per-line object, the class for the latter is just an stdClass, and the data from the file is essentially ignored. The script has two lines near the bottom that are method calls to ImportData(). Comment out one or the other to see the script run successfully or to see it fail. Option 1 works; option 2 fails. Note that I tested this under 5.3.6, not the 5.3.8 that's indicated on the bug. I do not have access to the latter. Expected result: ---------------- I'd expect the script to run to completion in all cases, assuming there is sufficient memory. Actual result: -------------- The script fails in the case of >= 10000 items in the array being converted. -- Edit bug report at https://bugs.php.net/bug.php?id=55660&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55660&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55660&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55660&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55660&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55660&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55660&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55660&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55660&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55660&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55660&r=support Expected behavior: https://bugs.php.net/fix.php?id=55660&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55660&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55660&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55660&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55660&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55660&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55660&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55660&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55660&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55660&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55660&r=mysqlcfg
