Summary	0000664: xdebug crash: kernel: pid 98370 (httpd), uid 80: exited on signal 11
Description	This bug is reported by one of the PhpStorm EAP users. It seems to be xdebug bug. We send 'feature_set max_depth -v 0' before sending 'context_get' in order to speed up debugging and it cause this problem. We cannot reproduce the problem in our test environment, but it is always reproducible on user side. Log attached. Related youtrack issue: http://youtrack.jetbrains.net/issue/WI-5092
Additional Information	FreeBSD 6.2, Apache apache-2.2.17, php52-5.2.17
Tags	No tags attached.
Attached Files	xdebug.log (4,127 bytes)

Operating System	FreeBSD 6.2

nnmatveev 2011-02-11 05:02 reporter ~0001670	From user comment: The xdebug log indicates that the following dbg command gets sent: "<- feature_set -i 10 -n max_depth -v 0 ->" If i patch the xdebug source to override max_depth -v 0 to max_depth -v 3 the debugging is working again. Even if xdebug should not crash max_depth 0 does not seem to be correct.

nnmatveev 2011-02-11 15:55 reporter ~0001671	From user comment: xdebug_handler_dbgp.c Add line 1546: if (options->max_depth == 0) options->max_depth =1; Works for me - without the line the http process crashes. (FreeBSD 6.2. RELASE, GCC 3.4.6)

derick 2011-03-10 20:51 administrator ~0001687	If you have easy access to the index.php script; that'd make it easier for me to reproduce this issue.

derick 2012-06-27 21:14 administrator ~0002303	Is this still an issue with the latest releases?

nnmatveev 2012-07-01 17:51 reporter ~0002313	I can't reproduce it on the latest release.

derick 2012-07-01 18:05 administrator ~0002314	All right; closing this one then.
