Description:
------------
Package used is php55u-pecl-xdebug-2.3.2-1.ius.centos6.x86_64. With xdebug enabled, if I run 'service httpd reload', then any requests to the server generate the following in the httpd/error_log:
[Mon Apr 27 16:31:27 2015] [notice] child pid 26233 exit signal Segmentation fault (11), possible coredump in /tmp/apachedump

Restarting the service fixes the problem. If I disable the config for xdebug, the reload does not cause this problem. My xdebug config is:

zend_extension=xdebug.so

xdebug.remote_host="xx.xx.xx.xx"
xdebug.remote_port="9000"
xdebug.remote_enable=1
xdebug.collect_params=4
xdebug.collect_return=1
xdebug.remote_log="/var/log/xdebug.log"
xdebug.profiler_output_dir=/tmp
xdebug.profiler_enable_trigger=1
xdebug.idekey='XDEBUG_NOTEPAD'


Actual result:
