OK.  The breakpoints seem to be failing because they are set on switch
statements or other locations that are not handled properly by the
debug code.  I tried a few quick things to fix it but wasn't
successful.  I don't understand the breakpoint/debug code very well
and don't have more time at the moment to debug it.  But you can see
that the breakpoints can work in methods and constructors if you do

  dbstop @gf/subsasgn 5

for example.
