Bug Type: PDO related
Operating System: Linux 2.6 / Apache2
PHP Version: PHP 5 CVS
Assigned To: wez
New Comment:
Tried again this morning with CVS snapshot php5-200507192230. Same
install routine which, this time, created and install the .so file
properly.
My test script now works fine, and I can run the unit tests
successfully. Big improvement!
However...
I'm still getting intermittent (like about half of the time I run the
PDO::SQLite tests) segfaults reported in Apache's error log.
Prehaps more worryingly, after trying to run the SQLite unit tests for
a while, I have seen what looks like some of the apache2 stuck in
infinite loops (three processs each using ~33% CPU -- I'm using the
Apache2 prefork MPM with APXS2 to build PHP).

Hmmm...
I think something screwy happened with the install of the latest
snapshot, making my last (good news/bad news) report suspect.
I did my usual install routine (on Debian 3.1):
make
apache2ctl stop
make install
apache2ctl start
Then tested the snippet using the CLI:
$ php -v
PHP 5.1.0-dev (cli) (built: Jul 19 2005 08:45:23 NZ)
$ php test.php
$ (no segfault!)
The 'bad news' came when I browsed to the unit test page normally --
but on further investigation it seems that the normal install process
failed on the snapshot.
For some reason 'make install' put the files libphp5.[a|la] in my
/usr/lib/apache2/modules, rather than the usual libphp5.so...
Has the build process changed, or have I done something stupid? ;-)
./configure --with-apxs2=/usr/bin/apxs2 \
--with-config-file-dir=/etc/php --with-mcrypt --with-gd \
--with-zlib --enable-exif --with-freetype-dir \
--with-jpeg-dir --enable-debug

Let's see the backtrace(s) for the problems here, before deciding what
else to do.

Just rebuilt and retested with php5-200507182030, thanks for the quick
response!
I've got good news and bad news:
The good news is that the latest snapshot doesn't segfault on the test
snippet above.
The bad news is that my full unit tests still cause PHP to segfault on
the SQLite tests...
What would you like me to do? I could:
1) Put together another snippet and post it here
2) As above, but create a new bug report
3) Post my classes somewhere for you to look at directly
Cheers,
Leon

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.

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.
