Bug #69411 [NEW]: Segmentation fault in _pcre_jit_compile

From: berdir Operating system: Linux PHP version: master-Git-2015-04-09 (Git) Package: PCRE related Bug Type: Bug Bug description:Segmentation fault in _pcre_jit_compile Description: ------------ This is part of our efforts to get Drupal 8 green on PHP 7, see https://www.drupal.org/node/2454439. One of our tests is failing with a segmentation fault. The strange part is that the test passes, and only after that, the segfault happens: $ php7 core/scripts/run-tests.sh --url http://d8/ --color --class "Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test" Drupal test run --------------- Tests to be run: - Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test Test run started: Thursday, April 9, 2015 - 22:59 Test summary ------------ Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test 793 passes Segmentation fault (core dumped) FATAL Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test: test runner returned a non-zero error code (139). - Found database prefix 'simpletest810509' for test ID 1765. Test run duration: 20 sec backtrace/lines with gdb: https://gist.github.com/Berdir/c9f4876f8f4fbd17b2cd (Those lines do not actually exist in that file, so I guess that's some jit magic? I don't really understand C). I can provide the core dump if that's useful. Happy to provide more information if I can. -- Edit bug report at https://bugs.php.net/bug.php?id=69411&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69411&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69411&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69411&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69411&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69411&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69411&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69411&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69411&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69411&r=support Expected behavior: https://bugs.php.net/fix.php?id=69411&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69411&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69411&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69411&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69411&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69411&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69411&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69411&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69411&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69411&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69411&r=mysqlcfg
