Patch to be added to the SOURCES

Description of problem:

Where ganglia-gmond is used to collect data from sflow (e.g. Windows machines,) the gmond service crashes when an XML file is requested.  This can be re-created using either telnet to the listening port or gstat -a.  This results in a segmentation fault.  

This was reported as an issue in Feb on the ganglia git hub page: https://github.com/ganglia/monitor-core/issues/246

I've since submitted details of the problem and how to fix it. 

I've attached a patch file, added this to the spec file of my rpm and confirmed that the rpm built with this works as expected with sflow.  

Version-Release number of selected component (if applicable):

ganglia-gmond-3.7.2-11

How reproducible:

Steps to Reproduce:
1. Install ganglia-gmond with default settings
2. Uncomment lines in config file to allow gmond to receive sflow packets
3. Configure another machine to send sflow data
4. Request the gmonds data in xml format, either using telent, gstat or from a gmetad collector. 

Actual results:

Segmentation fault. 

Expected results:

XML file output and the gmond keeps running.
