Description:
------------
Hello,

I am getting the following error when accessing a bit of code when the opcache is turned on:

"Program received signal SIGSEGV, Segmentation fault.
_zend_mm_free_int (heap=0x2ac92c0, p=0x7f2fa026db40) at /build/buildd/php5-5.6.6+dfsg/Zend/zend_alloc.c:2104
2104	/build/buildd/php5-5.6.6+dfsg/Zend/zend_alloc.c: No such file or directory."



I have narrowed it down to this line in one of the many classes in the application:

}elseif (!is_file($file) || !is_readable($file)) {

If this line gets commented or opcache is off then there are no problems and the code executes fine.

The interesting thing is if I call this class from a different program there are no errors when opcache is turned on.  Seems it only happens when the class is used with a specific order of events.  For that reason, I haven't been able to provide replication code.


Attached is the gdb backtrace.  I hope this helps and please let me know if you have anymore questions.

A couple of things I notice here:

1. The crash is on a call to file_put_contents() and it looks like it is trying to write to a Doctrine stream of some kind
2. I see dtrace all over the backtrace which is kind of weird

Hi Rasmus,

Thanks for the reply.  But I'm not sure what it means.  I can give you a bit more info about what's happening at the time it crashe, if that helps.

Well, there are a couple of things going on with files here.  First we're getting an uploaded file and using ZF2's MimeType filter to check the file.  The MimeType filter is are using the methods is_file() and is_readable() noted above and are looking through a list of known mime files to get the definitions.  Some of these files may or may not be there.  Once it finds it, it reads the file to get a list of mime types.  Once it has that it checks the uploaded files mime type to see if it's in that list.

From there we are uploading the file via the s3 stream (Zf2 AWS SDK module) and then storing the path into the DB, which as you noted is using Doctrine for the back end, which will attempt to write a proxy file if it can't find one.

Using your comments I double checked the directories and PHP can certainly write to the destination folder.

As noted earlier, with opcache turned off, everything works fine.  In fact if I restart the server the first request works but the additional requests fail when the opcache is turned on.

I have worked around this issue by simply putting that MimeType filter in the opcache blacklist for now and that got it working.

Is there anything else you'd recommend I try, or any additional information I can get you?

Thanks again,
Westin Shafer

Additional information: Downgraded to php 5.5.22 and this issue doesn't happen on this version.
