 I believe I have done this properly and copied the resulting library
 and debug file to the test system.
 
 Repeating the test reveals no new information.  This time, there were
 only three frames in the backtrace.
 
 #0  0x00007f7ff7821f26 in ?? ()
 #1  0x0000a50000000000 in ?? ()
 #2  0x0000000000000000 in ?? ()
 
 The first backtrace address is in libcurses, but no debugging information
 is available.
 
 The second frame address seems to be garbage and doesn't appear in the
 pmap listing at all (i.e., the longest matching address is 0000 which
 matches everything).   The third frame is the 'mplayer' executable.
