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.
Actual result:
