Bug #63305 [NEW]: zend_mm_heap corrupted with traits
From: johan dot groth at sorona dot se
Operating system: Windows 7 64-bit
PHP version: 5.4.7
Package: Scripting Engine problem
Bug Type: Bug
Bug description:zend_mm_heap corrupted with traits
Description:
------------
Note: This problem appears on 5.4.8 as well, but it was not available in
the list when I created the report.
Sometimes when using traits, I get "zend_mm_heap corrupted". I get it both
while running under apache and while running from the command line. It's a
problem under apache, since then I do not get any output sent to the
browser. If I run the same script on the command line, I get output but
with "zend_mm_heap corrupted" at the end. So, the script seem to finish
every time but with an error afterwards.
I have gotten this error in the past a few times, but could solve it every
time by upgrading to a newer release of PHP. Now however, I'm on the latest
release and have run into this problem yet again. It seems really hard to
reproduce, and I have not been able to do it in a test script, it only
appears when I run my full application and only when using traits.
These bugs seem to be related:
#62339
#55382
#62358
I have tried to generate a dump according to these instructions:
https://bugs.php.net/bugs-generating-backtrace-win32.php
However, I have not been able to get something useful out of it. It seems
that the program does not detect that a crash has occured, even if it says
the following in the apache error log:
zend_mm_heap corrupted
[Thu Oct 18 15:35:12 2012] [notice] Parent: child process exited with
status 1 -- Restarting.
Test script:
---------------
I have not been able to reproduce this problem in a test script.
Expected result:
----------------
Not "zend_mm_heap corrupted"
Actual result:
--------------
zend_mm_heap corrupted
