This is happening reading an annotation, can you check what annotation is causing this?

Related: #10140 (comment)

[virgofx]

I'm trying to reproduce the issue and it appears randomly on our test application ... in general, we use the annotations memory adapter (files in production) for our model metadata as described here:

http://blog.phalconphp.com/post/47471246411/tutorial-creating-a-custom-models-initializer

We did extend the functionality to provide a few additional event callbacks. I'll try to provide more info -- I'm going in order trying to isolate all these segfaults with proper gdb trace enabled.

[patrick-zippenfenig]

Could you run phalcons unit-tests?

curl -sS https://getcomposer.org/installer | php
php composer.phar install
gdb --args php ./unit-tests/ci/phpunit.php --debug -c unit-tests/phpunit.xml --testsuite=stable
(gdb) run

I most likely can reproduce the same behaviour:

[andresgutierrez]

This is now fixed in 2.0.x, could you please try again using this branch?

[virgofx]

I've confirmed the error is no longer happening in the unit-tests as of latest commit.

Since I also was able to reproduce this intermittently using our internal dev application, I'm going to run using latest 2.0.x all day just to make sure I don't see this as well and then confirm later tonight/tomorrow.

[patrick-zippenfenig]

👍 works

[andresgutierrez]

@virgofx Could you please close this if it is fixed?

[virgofx]

@andresgutierrez Sorry for the delay ... was testing using the latest changes this week in our main app environment and I didn't notice anything specific that would lead me to believe the issue is still there. I'm trying to isolate a few other issues which I believe are un-related. Marking as fixed.
