msamson at chowly dot com: I reproduced your script, though no crash at
all.





./../sapi/cli/php -v

[2011-04-08 15:50 UTC] msamson at chowly dot com : Can you post the gdb
backtrace 

or a reproduce script ? and script that requires a framework or a third
party 

extension is NOT reproduce code.

No, the crash also occurs when the mongo.so extension is not loaded.



At first, it thought it was the culprit, but it happens without mongo
being 

loaded.



One thing, the CLI version seems to be more resilient, it needs more
data loaded 

to crash, whereas with the apache module, it's always crashing.



Chromium reports `Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error`
when 

accessing a url.



I was able to get a backtrace (with no execute or zbacktrace output) and
around 

frame 30-ish, it specifies entering the shutdown sequence, cleaning up a
closure 

and then the crash.



Changing the summary to better reflect the problem.
