Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip Works for me with CVS HEAD. Please try the snap dated after this message to confirm. Previous Comments: ------------------------------------------------------------------------ [2005-07-18 01:31:49] leon at lost dot co dot nz Whew... All done... I've pared my script from > 1800 lines of PHP scattered accross 7 files to three lines in one file! Turns out to be a SQLite PDO problem... <?php $conn = new PDO('sqlite::memory:'); $sql = "SELECT name FROM sqlite_master WHERE type='table' ORDER BY name;"; $conn->query($sql); ?> This snippet causes PHP5.1b3 to segfault everytime (I'm using the bundled SQLite library). One of my other unit tests still throws up that corruption I talked about before, but I'll try to isolate that and submit a brand new bug report for that. ------------------------------------------------------------------------ [2005-07-18 00:39:46] leon at lost dot co dot nz Yahoo! I couldn't wait, and have already produced a single PHP file that segfaults the command line version of PHP-5.1b3 routinely. If you want it now let me know -- I'm currently just in the process of trying to whittle it down to it's essential elements... ------------------------------------------------------------------------ [2005-07-18 00:14:08] leon at lost dot co dot nz Okay, I understand. It's going to be tough -- I have objects creating other objects, dynamically including other class files, etc..., but I'll give it another crack tonight (New Zealand time). Cheers, Leon ------------------------------------------------------------------------ [2005-07-17 23:48:18] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. We really need a reproducable script... ------------------------------------------------------------------------ [2005-07-17 23:44:33] leon at lost dot co dot nz Description: ------------ My fairly complex object orientated PHP5 app consistently segfaults when trying to run code with particular parameters. I've been trying to fix this problem since 5.1b1, through lots of recent CVS snapshots, and now this morning with 5.1b3 -- I'm now pretty sure it's a PHP problem. The code in question is my apps unit test framework. A tester object dynamically creates instances of my application's objects as well as a test class for each app. object. The tester runs methods in the test class against the app. object. $testObject = new $testClassName(); The same page is run with the names of class to be tested as a parameter. Currently, it consistantly segfaults when trying to test my PDO SQLite wrapper, although it is giving 'unusual' warnings (I suspect memory corruption, for reasons given below) when testing another object (a mcrypt wrapper): NOTICE: Use of undefined constant - assumed '' There are about 20 other objects that test fine. Reproduce code: --------------- Unfortunately I have not been able to produce a snippet that reproduces the behaviour -- the same PHP code seems to work great with some inputs. I'm not sure what more to do for now. I'll run whatever tests you like to try to get to the bottom of the problem. Actual result: -------------- As well as the segfault described above I have also seen, with the same test, memory corruption in a previous snapshot of PHP5.1 -- PHP 'notices' about undefined constants where the constants are long strings of what looked like completely random data. Backtrace of last segfault: -------------------------- # gdb /usr/sbin/apache2 ... (gdb) run -X .... Program received signal SIGSEGV, Segmentation fault.
