We have experienced a number of show-stopper problems with PHP 5.1.2 as distributed with Dapper. These manifest themselves as segmentation faults in the Apache2 log (with no further information), e.g. "[notice] child pid XXXXX exit signal Segmentation fault (11)" and affect all manner of complex applications. For instance, the code embedding Gallery2 in Drupal is affected (and this is a key component of many of our commercial offerings) - resulting in blank screens and no other useful debug info, see: http://www.galleryembedded.com/forums/viewtopic.php?p=20500#20500
Note that based on the large number of views of this issue on the galleryembedded site, we're not alone in being affected by this problem. As a possible workaround, we have installed "DotDeb"'s PHP 5.1.4 packages on a test machine, and although there are rather tricky dependency issues, we found that our application worked flawlessly following the upgrade, indicating that one of the bug fixes in 5.1.3 or 5.1.4 has addressed the problem. We not only maintain a Ubuntu Dapper-based hosting infrastructure, but also roll out and maintain a signficant number of Dapper boxes for clients (all of whom have PHP apps) and would be thrilled to see 5.1.4 back ported to Dapper (particularly if it included in-built tidy support!!). If the Ubuntu team doesn't feel it's worthwhile doing it, we will attempt to do it ourselves. Is there anything we can do to help the Ubuntu team tackle this problem?
