Segfault in phalcon.so


I'm working in PHPEd and have DBG extension enabled in php.ini.

When in debugging mode, I'm getting the following error string in /var/log/syslog:

php kernel: [ 187.433356] php-fpm[1822]: segfault at 0 ip 00007f29d46a7c40 sp 00007fffdaac4c50 error 4 in phalcon.so[7f29d4660000+259000]

If I'm at a breakpoint #1 and continue execution in debugger, I usually arrive at the next breakpoint without a problem. However, first stepping over the next line of code and THEN continuing execution, crashes it for certain.

The behaviour is really erratic and the whole setup is rather hard to reproduce/describe. I'm working on a Phalcon\Mvc\User\Plugin class and I have two listeners attached to Dispatcher's "dispatch" event.

Anything else I can do to help diagnose the problem?

Thanks, Temuri


Can you install again compiling from master? (using current changes into it)

Is it possible to generate a core dump?

You may want to try

ulimit -c unlimited
/etc/init.d/php-fpm restart

and then watch for core or core.XXX files



I changed the way my script works, upgraded to 1.2.1 and can no longer reproduce this behaviour.

I suppose, problem's solved. But I'll definitely keep an eye on it.

Thanks again, Temuri
