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. we really need a testscript or backtrace to diagnosis the problem Previous Comments: ------------------------------------------------------------------------ [2012-10-18 14:08:33] johan dot groth at sorona dot se 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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63305&edit=1
