#47724 [NEW]: Reproducable segmenation fault using symfony and doctrine

From: scott at danielfamily dot com Operating system: Centos 5.2 PHP version: 5.2.9 PHP Bug Type: Reproducible crash Bug description: Reproducable segmenation fault using symfony and doctrine Description: ------------ Sorry for the longer than asked for initial post, but I've spent many many hours profiling this problem to make this bug report. Our project uses symfony framework with the doctrine database abstraction. We have had a number of crash sequences that are VERY hard to simplify and usually crash intermittently. I have isolated an instance that always crashes on our linux systems and usually crashes under windows. If I change the order of code or add code, the problem may disappear temporarily only to resurface later after additional code modification have been made. I've done this several times, but have no confidence in deploying this kind of fix in a final released product. After many many hours, I've built a vmware appliance with Centos 5.2 and the LAMP stack installed. It was built using the latest Apache and PHP source. It is built using the enable-debug switch and I've gotten a stack trace (included below). Running the vmware appliance and hitting a single url running from it's server causes the error every time. If someone is assigned to this problem and communicates with me, I can send them the vmware appliance to run under windows. It is already setup with the software stack to reproduce and debug the problem. It should save many hours of configuration (at least it would for me). I believe that it is very possible this related to Bug #40479. Unfortunately, I have some experience with this problem with another project and believe it is a very serious unresolved issue.
