sendto() crashes my sun

[Dennis F. Reed]

i sent this in a couple weeks ago, but no response, so...

i have a simple(?) application developed on a 4.3bsd vax which uses unix
domain datagram sockets to communicate between processes.  most packets
are small (<128 bytes).  i moved it over to a sun-3 running sunos 3.5
(also tried a sun-2 running 3.4) and it appears that when a process calls
sendto(), the system crashes with the message:

panic: sbappendaddr

is this a know problem?  is there a workaround?  the system doc seems to
indicate the system call syntax is the same, so?????  help!  thanks!
