Unfortunately, I am not (yet) a programmer.  I had never really used 
'gdb' before Yves-Alexis asked me to in this thread.  And, while I am 
familiar with C and C++, I have never used the libraries required by 
this package's source code.

With that lack of background, I tried to create the safest fix I know 
how -- which turns out to involve about 9 changed lines instead of one.

Thank you for the response.  Part of my purpose in posting the patch was 
to get other eyes on the problem, under the (very likely) assumption 
that there was something wrong with my approach... or at least a better way!
