Command line and complete compiler output

The compiler generates a stringop-overflow because it believes there is region
size of zero which is being written a signal character into a (embedded 2
dimensional) array.  I've tried several different work arounds but doesn't seem
to .

I have included the compiler version/system/etc in gcc.txt and the complete
command line and output in cmd.txt.  The preprocessed files are also attached.
