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.
