ptrace, freebsd and vmware dont get along?

[Darren Reed <darrenr_(_at_)_freebsd_(_dot_)_org>]

using -current...

gdb does not seem to get along well under vmware...
doing "gdb a.out" with a "break main" followed by
"run" results in the behaviour seen here:
...
ptrace(0x21,0xebbe,0xbfbfdc90,0x0,0x28277130)    = 0 (0x0)
ptrace(0x25,0xebbe,0xbfbfddd4,0x0,0x8)           = 0 (0x0)
ptrace(0x7,0xebbe,0x1,0x14,0x10202)              = 0 (0x0)
wait4(0xffffffff,0xbfbfdf08,0x0,0x0,0x28369569)  = 60350 (0xebbe)
kill(60350,0)                                    = 0 (0x0)
ptrace(0x21,0xebbe,0xbfbfdc90,0x0,0x28277130)    = 0 (0x0)
ptrace(0x25,0xebbe,0xbfbfddd4,0x0,0x8)           = 0 (0x0)
ptrace(0x7,0xebbe,0x1,0x14,0x10202)              = 0 (0x0)
wait4(0xffffffff,0xbfbfdf08,0x0,0x0,0x28369569)  = 60350 (0xebbe)
kill(60350,0)                                    = 0 (0x0)
ptrace(0x21,0xebbe,0xbfbfdc90,0x0,0x28277130)    = 0 (0x0)
ptrace(0x25,0xebbe,0xbfbfddd4,0x0,0x8)           = 0 (0x0)
ptrace(0x7,0xebbe,0x1,0x14,0x10202)              = 0 (0x0)
wait4(0xffffffff,0xbfbfdf08,0x0,0x0,0x28369569)  = 60350 (0xebbe)
kill(60350,0)                                    = 0 (0x0)
ptrace(0x21,0xebbe,0xbfbfdc90,0x0,0x28277130)    = 0 (0x0)
ptrace(0x25,0xebbe,0xbfbfddd4,0x0,0x8)           = 0 (0x0)
...

and gdb goes out to lunch without returning.  And with a ^C,
I get it all nice and hung up:
60349  p0- TX     0:27.46 gdb a.out
60350  p0- TX     0:15.39 /bin/csh -c exec /usr/home/darrenr/a.out
60369  p4  I+     0:00.20 truss -p 60349

It requires a "kill -9" on the truss to restore life.

Does anyone have any ideas about where to start trying
to resolve this problem?

Thanks,
Darren
