Description:
------------
i can't identify the problem yet but php simply crash when i include a file

the included file is executed totally but at the end something goes wrong

(it is not a simple include, i'm trying to identify the code that crashes apache)

according to windows php snaps:

     Tuesday, August 02, 2011 11:52 AM        <dir> r314086 <-- this crashes
... and crashes with latest snap too

not sure if it is related because it is not logged at every page load, but sometimes apache logs "zend_mm_heap corrupted"

thanks in advance

Do you have any extensions like Xdebug, APC or other extensions that may hook into the include construct?

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

can I use the "without compiler method" to provide a backtrace of php as apache module? I don't think it is related to apache but i will probably need a webserver to run the evil script
 [2011-08-22 18:27 UTC] pajoye@php.net 
Yes, it is enough and if you can provide a script to reproduce it, even better.

hello, I've tested with the latest head of the branch and now works good, so this was fixed in these months

sorry for taking a long time to provide feedback, but providing a bug report is a total pain, at least on windows.

I really like the new php release process, but it is not compatible with the actual testing/debugging process. I think php should reinvent its beta testing by reaching "normal people" too. I'm not a computer hacker, but i should be able to provide a debug report, but at the moment is really too hard to do.

See how mozilla works, debug report is embedded and easy to use, nightly and aurora builds are accessible to every audience, included "noobs", if they are interested into debugging.

I think php should do as mozilla is doing!

btw I'm setting this as resolved, who knows what was the bug, now works perfectly ;)
