[BUG] Latest build of Phalcon 1.3.0 is crashing PHPEd

[temuri416]

I had not updated 1.3.0 in about 6-7 weeks. Did that just a moment ago and my PHPEd debugger started crashing when breakpoint is triggered.

I cloned/compiled 1.2.4 - no problem there.

The message:
Fatal error while fetching local variables. Debug session has been terminated.

The following is being added to /var/log/kern.log:

kernel: [ 2213.378010] php-fpm[24084]: segfault at 282 ip 00007f87aef644de sp 00007fffbe358110 error 4 in dbg-php-5.5.so[7f87aef4d000+23000]

Also, there's a huge dump file created: /var/crash/_var_web_php_sbin_php-fpm.33.crash.

I started checking out commits by ID in reverse chronological order and found that problems started with commit ID

d21bbf9a779dfbb8598ec8608de60b27cf30d927 (12/11/2013 by Andres - Regenerating build [ci skip])

The one before it works fine.

Please help! :-)

Thanks!

Could you please generate the backtrace?

gdb /path/to/php-fpm /path/to/core/dump

and then at gdb prompt run

I was finishing editing my post when you wrote that. Please read the edits.

Where do I find "/path/to/core/dump" ?

[temuri416]

"/var/crash/_var_web_php_sbin_php-fpm.33.crash" is not a core dump: File format not recognized

Are you using Ubuntu?

[temuri416]

yes

Run this as root:

cd /var/crash
apport-unpack _var_web_php_sbin_php-fpm.33.crash /var/crash/unpacked
chmod a+rX -R /var/crash/unpacked

then (i think this can be run as the ordinary user):

gdb /var/web/php/sbin/php-fpm /var/crash/unpacked/CoreDump

Does it run fine without the debugger?

[temuri416]

Yes.

OK, could you please build Phalcon from ext/ in debug mode and try again? This should produce more meaningful backtrace.

cd ext
phpize
./configure CFLAGS="-O0 -g3"
make -j4
sudo make install

Gotta step out.. Will be available next morning. Please let me know if you figure anything out.

Clearly, something in that commit broke the debugger.

Thanks!

I'm back... Any thoughts? This is an absolute nightmare scenario for me. I'm too far into my project to start again. And no debugger is a disaster...

This backtrace looks totally different — though it is possible that the crash happened in the same place as before, it was triggered by a different code path.

The first crash happened when Phalcon\Validation\Message\Group::valid() was called, the second one happened when Phalcon\Dispatcher::dispatch() called the controller/action handler.

Is there any source code for dbg-php-5.5.so or is it proprietary?

Also is there a way to run php under valgrind?

I am running the tests under valgrind: https://travis-ci.org/sjinks/cphalcon/builds/15769025 to see if it detects anything wrong.
