• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Aleksey Egorov 2014-03-02 13:27:38 UTC]

Crash if I use option xdebug.collect_return with Symfony framework.

Reproducible: Always

Steps to Reproduce:
1. install php-5.5.9-pl0-gentoo with xdebug and run it as php-fpm with nginx
2. enable option xdebug.collect_return
3. install Symfony framework and try to open any page. 502 bad gateway error.
Actual Results:  
Segmentation fault

Expected Results:  
I should be able to open page without any errors.

if I remove option collect_return, then php do not crashes.

This looks similar to http://bugs.xdebug.org/view.php?id=1047

[Comment 2 Brian Evans (RETIRED) 2016-08-01 18:14:46 UTC]

Please confirm if this is still an issue with xdebug-2.4.0.  The upstream bug OP reports no further issues with that version.

[Comment 3 Michael Orlitzky 2017-01-02 23:16:21 UTC]

Since we think this was a (now fixed) upstream bug, we need confirmation that the issue still exists, if it does. If we don't hear back from you, we'll have to close this as NEEDINFO sooner or later.

[Comment 4 Aleksey Egorov 2017-01-03 08:04:30 UTC]

By this moment, I'm using another version of php, xdebug and symfony. Yes, it works fine on my system :)

[Comment 5 Michael Orlitzky 2017-01-03 13:32:23 UTC]

Glad to hear it, thank you!
