From: berdir Operating system: linux PHP version: 5.4.8 Package: Reproducible crash Bug Type: Bug Bug description:segmentation fault in zval_mark_grey()
Description: ------------ I'm experiencing segfaults in the mentioned function while working on Drupal 8. Here's what I found out so far: - Happens both with the default ubuntu 12.04 php 5.3.10 and php 5.4.8 from https://launchpad.net/~ondrej/+archive/php5 - See http://drupal.org/node/512026#comment-6673974 for the backtrace - Happens both on my local installation and our automated testbots - The segfault does not happen if zend.enable_gc is Off. It's non-trivial to set up, see "script" below, so just tell me what commands to run in gdb to give you additional information if required. Test script: --------------- git clone g...@git.drupal.org:project/drupal.git --branch=8.x # Install Drupal, enable Testing module. wget http://drupal.org/files/form-state-keyvalue-512026-98.patch git apply form-state-keyvalue-512026-98.patch php core/scripts/run-tests.sh --class "Drupal\views\Tests\Handler\FilterStringTest" Expected result: ---------------- Drupal test run --------------- Tests to be run: - (Drupal\views\Tests\Handler\FilterStringTest) Test run started: Wednesday, October 31, 2012 - 23:50 Test summary ------------ Filter: String n passes, 0 fails, and 0 exception Test run duration: n sec Actual result: -------------- Drupal test run --------------- Tests to be run: - (Drupal\views\Tests\Handler\FilterStringTest) Test run started: Wednesday, October 31, 2012 - 23:50 Test summary ------------ Segmentation fault (core dumped) FATAL Drupal\views\Tests\Handler\FilterStringTest: test runner returned a non- zero error code (139). - Found database prefix 'simpletest916618' for test ID 372. - Removed test files directory. - Removed 43 leftover tables.
