[Bug 418220] Re: apache2 crashed with SIGSEGV in pdo_parse_params()
I traced the problem to a bug in ext/pdo/pdo_sql_parser.c that must have been introduced somewhere around 5.2.6. I started working on a fix but then thought to replace that file with one from a newer version of PHP. I tried replacing with the one from 5.2.10.dfsg.1-2ubuntu4 and the bug had already been fixed in that version. It looks like a fix was submitted almost a year ago in bug: http://bugs.php.net/bug.php?id=44251 I've attached a diff of the changes between 5.2.6.dfsg.1-3ubuntu4.2 and 5.2.10.dfsg.1-2ubuntu4 in case you want them, but you may consider this already fixed since it is at least fixed in 5.2.10 which will come out in Karmic. Using the Karmic package works fine for me, but it would probably be nice if it was backported to Jaunty for other people.

[Bug 418220] Re: apache2 crashed with SIGSEGV in pdo_parse_params()
I have been analyzing the differences between my Jaunty server which has the segmentation fault problem, and a Jaunty virtual machine which works fine. I've determined the key difference: The problem machine has package php5-mysql (version 5.2.6.dfsg.1-3ubuntu4.2) installed. To eliminate the segmentation fault, I installed a different (apparently older) version of pdo and pdo_mysql by doing sudo pecl install pdo_mysql which overwrote Ubuntu's installed pdo and pdo_mysql libraries. These modified libraries are found at /usr/lib/php5/20060613/pdo.so and /usr/lib/php5/20060613/pdo_mysql.so. Key file version differences: pdo.c: BAD: 1.57.2.17.2.10.GOOD: 1.57.2.17 pdo_dbh.c: BAD: 1.82.2.31.2.22.GOOD: 1.82.2.30 pdo_sql_parser.c: BAD: 1.35.2.6.2.15 ...GOOD: 1.35.2.6 pdo_sql_parser.re: BAD: 1.28.2.4.2.12...GOOD: 1.28.2.4 pdo_sqlstate.c: BAD: 1.7.2.1.2.2..GOOD: 1.7.2.1 pdo_stmt.c: BAD: 1.118.2.38.2.34GOOD: 1.118.2.38 php_pdo_driver.h: BAD: 1.66.2.11.2.8...GOOD: 1.66.2.11 php_pdo.h: BAD: 1.7.2.5.2.4...GOOD: 1.7.2.5 mysql_driver.c: BAD: 1.59.2.13.2.6...GOOD: 1.59.2.13 mysql_statement.c: BAD: 1.48.2.14.2.7...GOOD: 1.48.2.14 So the file versions are very close so there wasn't much changed between them. It looks like the newer version either had a bug introduced that causes this segmentation fault, or it is also possible that the way the Ubuntu package was compiled is causing a problem I suppose? I don't know much about the internals of this library so is there someone who is familiar with the internals of PDO comment? Thanks.

[Bug 418220] Re: apache2 crashed with SIGSEGV in pdo_parse_params()
I just built the pdo.so and pdo_mysql.so library files from the Ubuntu source package by doing apt-get -b source php5-mysql and then copying those 2 .so files to /usr/lib/php5/20060613 and restarted Apache. The segmentation fault happened in the same way. This seems to indicate that there was a bug introduced with this newer version and the problem probably wasn't with the way the package was compiled. -- apache2 crashed with SIGSEGV in pdo_parse_params() https://bugs.launchpad.net/bugs/418220 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 418220] Re: apache2 crashed with SIGSEGV in pdo_parse_params()
I was able to get the test libmysqlclient15off package properly installed and I tested with it and confirmed that that did fix the case reported in bug 524366, BUT unfortunately it did not fix my bug as I've reported here. It happens in the exact same way. So if it is actually caused by the same bug as https://bugs.launchpad.net/ubuntu/+source/php5/+bug/343870 then that fix doesn't work on my bug, otherwise it is a different bug. Since that bug was related to a race condition that affected multiple cores, I disabled all but one core using the maxcpus kernel boot option and the bug still occurred. ** This bug is no longer a duplicate of bug 343870 php-cli segmentation fault with mysql extension -- apache2 crashed with SIGSEGV in pdo_parse_params() https://bugs.launchpad.net/bugs/418220 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Hi, where does this: #2 0x7fb51a1354d2 in xdebug_execute_internal ( current_execute_data=0x7fff2af4ef70, return_value_used=1) at /build/buildd/xdebug-2.0.3/build-php5/xdebug.c:1605 edata = (zend_execute_data *) 0x7fff2af4ef70 fse = (function_stack_entry *) 0x7fb5246ab4c0 cur_opcode = (zend_op *) 0x1 do_return = 0 function_nr = 266972 come from? (Is that packaged php5-xdebug? What version?) Is the bug reproducible? Could you try disabling xdebug, and trying to reproduce the problem? Or could you try setting up karmic virtual machine and trying to reproduce it there?

[Bug 418220] Re: apache2 crashed with SIGSEGV in pdo_parse_params()
Hello Ondrej, Thanks for the response. Yes, that line was from package php5-xdebug. I had tried using that package to help track down the bug. I uninstalled it and the crash still occurs in the same way, only the stacktrace now doesn't include the xdebug part of course. The bug is reproducible in that I created a simple test case which causes the crash about 90% of the time. I'm not sure why the other 10% of the time the crash does not occur. Yesterday I created a Jaunty Server virtual machine and tried my test and the crash did not occur under the virtual machine. I am currently trying to figure out what, if any, differences there are between my physical computer and the virtual machine, other than my physical machine is running Jaunty (plain) and the other is Jaunty Server. All the PHP and Apache packages are the same version.

I guess this could be same bug as in http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=402181 The solution is also same, ask your vendor to fix binary compatibility or don't use packaged php5. ** Bug watch added: Debian Bug tracker #402181 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=402181 -- apache2 crashed with SIGSEGV in pdo_parse_params() https://bugs.launchpad.net/bugs/418220 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
