23 # This test really needs some major surgery to be acceptable, but
24 # I'm just about burnt out on lynx work, so I'm not doing it now.
26 # * The test has an indeterminate number of pass/fails
27 # for each run (it runs a small group of tests until
28 # it's timer kicks off). This is very bad for nightly
29 # automated regression testing.
31 # * It tries to "step" from withint he prologue of a
32 # function. This isn't support in gdb (it's going
33 # to act like a continue).
35 # * This test rarely check that it stopped in sensible
36 # places. (see previous bullet -- this test doesn't
37 # catch the fact it continued rather than stepped)
