[asterisk-commits] murf: branch 1.4 r158603 - /branches/1.4/res/res_features.c

[SVN commits to the Asterisk project]

New Revision: 158603

URL: http://svn.digium.com/view/asterisk?view=rev&rev=158603
Log:
In reference to the fix made for 13871, I was
merging the fix into 1.6.0 and realized I missed
the code in the h-exten block, and didn't catch it
because my test case had the h-exten commented out.

So, this corrects the code I missed, as a 
preventative against another crash report.
Tested with the h-exten defined, all is well.
