Summary0000837: xdebug crashes on some breakpoints
Description

I am using PHPStorm to debug scripts. After upgrading to PHP 5.4.3 and XDebug 2.2.0 debugging process become impossible in some random places in code. The project is large. I create a breakpoint, run debugging, PHP stops on this breakpoint and crashes immediately. Entire PHP process is crashed and terminated.

XDebug writes this log:

Hi!

Thanks for this report, but for it to be really useful, I would also need a short standalone script that reproduces the problem. Could you please help in narrowing down your code base and provide such a script please?

cheers,
Derick

Hi! I uploaded simple example which reproduces the problem. Download the LightOpenId library, put the 'openid.php' file near the sample, set breakpoint on the '$oid->validate();' line and try to debug this method.

Derick, any progress on this? Did you manage to reproduce the crash with the sample submitted by speller on 2012-05-18?

I managed to trim speller's example to one file under 20 lines. This is the smallest version that crashes reliably on my machine, and when I remove further members from the class, it crashes only sometimes. This means that it might not work for you - in this case please paste a few more class members back from openid.php (also attached).

Set a breakpoint at the last line (exit;).

What is your gcc version btw.?

Rulatir, I just tried with your script but no luck. Could I see your phpinfo() section on Xdebug and the remote log that belongs to a debugging session that crashes (from the script you posted)?

I think I've just pushed a fix to github for this issue. Could you please try it?

Derick, can you provide compiled version for Windows to test this bug?

Seems issue is fixed in the master version. The example I provided do not crashes. Will check it in work.
