Bug #69411 [Asn->Fbk]: Segmentation fault in _pcre_jit_compile

Edit report at https://bugs.php.net/bug.php?id=69411&edit=1 ID: 69411 Updated by: cmb@php.net Reported by: berdir@php.net Summary: Segmentation fault in _pcre_jit_compile -Status: Assigned +Status: Feedback Type: Bug Package: PCRE related Operating System: Linux PHP Version: master-Git-2015-04-09 (Git) Assigned To: laruence Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2016-08-20 13:24:54] cmb@php.net > The _pcre_jit_compile segfaults might still exist, but they are > not stable, so they don't happen all the time.

In doubt, try with newer PCRE. ------------------------------------------------------------------------ [2015-04-20 08:03:49] berdir@php.net Sorry, didn't see the comments here before. https://bugs.php.net/bug.php?id=69484 might have fixed the curl related segfault that I've seen here. You're running the migrate tests with sqlite, they are currently not working, try the same with mysql. However, as I said in the other issue, that one might have fixed this problem and we actually committed a workaround for this test. The _pcre_jit_compile segfaults might still exist, but they are not stable, so they don't happen all the time. I will get back to this... ------------------------------------------------------------------------ [2015-04-12 07:21:01] hzmester at freemail dot hu Just a note: strange malloc errors could be caused by buffer overflows. Malloc stores descriptors of allocated/unused memory in the memory, and when a buffer overflow happens, that data might be damaged. Especially on buffer underflows, since this data is usually before the allocated block. However, the crash happens only when the malloc/free is called again. I recommend to use valgrind. If you use any kind of jit, don't forget --smc-check=all. ------------------------------------------------------------------------ [2015-04-11 09:54:08] laruence@php.net hmm, I was really upset that I can not make the test run as you described... I am using the drupal 8.0.x branch. the last commit is: commit b75b691a47eea31515d336065e8a3ec53423e0bd Author: Alex Pott <alex.a.pott@googlemail.com> Date: Thu Apr 9 18:53:33 2015 +0100 Issue #2463417 by rpayanm, cilefen, hussainweb: Clean-up remaining test members in module tests - ensure property de finition and use of camelCase naming convention And here is what I got while running it with --verbose: $ /home/huixinchen/local/php-trunk/bin/php core/scripts/run-tests.sh --url http://d8/ --color --verbose --sqlite /tmp/test.sqlite --dburl sqlite://tmp/db.sqlite --class "Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test" Drupal test run --------------- Tests to be run: - Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test Test run started: Saturday, April 11, 2015 - 09:52 Test summary ------------ Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test 1 passes 1 exceptions Test run duration: 42 sec Detailed test results --------------------- ---- Drupal\migrate_drupal\Tests\d6\MigrateDrupal6Test ---- Status Group Filename Line Function -------------------------------------------------------------------------------- Pass Other MigrateTestBase.p 52 Drupal\migrate\Tests\MigrateTestBas Enabled modules: action, aggregator, block, book, comment, contact, block_content, datetime, dblog, entity_reference, file, forum, image, link, locale, menu_ui, node, options, search, simpletest, statistics, syslog, taxonomy, telephone, text, update, views, migrate_drupal, migrate Exception Uncaught e Connection.php 609 Drupal\Core\Database\Connection->ha Drupal\Core\Database\DatabaseExceptionWrapper: SQLSTATE[HY000]: General error: 1 table &quot;content_field_multivalue&quot; has more than one primary key: CREATE TABLE {content_field_multivalue} ( vid INTEGER PRIMARY KEY AUTOINCREMENT CHECK (vid&gt;= 0), nid INTEGER NOT NULL CHECK (nid&gt;= 0) DEFAULT &#039;0&#039;, field_multivalue_value NUMERIC NULL DEFAULT NULL, delta INTEGER NOT NULL CHECK (delta&gt;= 0) DEFAULT &#039;0&#039;, PRIMARY KEY (delta) ); ; Array ( ) in Drupal\migrate_drupal\Tests\Dump\DrupalDumpBase-&gt;createTable() (line 53 of /home/huixinchen/drupal/core/modules/migrate_drupal/src/Tests/Dump/DrupalDumpBase.php).

InstallerTranslationTest, as commented above does seem to segfault there. Not sure what I should do now, possibly open two separate issues? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
