There is at least one symbol that is shown as having no machine code in
the DWARF info but obviously contains machine code if inspected using
objdump. This results in an exception being thrown when that symbol's
coverage map is looked up. That exception is now caught and a message
is printed to stderr rather than crashing the program.
