Oh, I'm sure there are lots.  Some are gdb varients, some not.  For example, do
you consider ROM monitors used in many embedded eval boards?  There are many of
these.  For example, I've think I've run into 4 or 5 different 'bug'
implementations in the Motorola world (both 68k and powerpc).  When I worked at
Data General, 10 years ago, I recall that there were something like 5 different
inhouse debuggers in the mainline OS, at least one of which they had lost the
sources to years before.
