[Samba] net rpc vampire segfault

[taso]

Been trying to run this on FC3 pulling stuff off a NT4 PDC - it just segfaults on 3.0.21 & 3.0.21a
I'm building the RPMS from the tar ball on the host using the makerpms.sh script

Reverted to the 3.0.10 issued by Fedora and no segfault.

 From what I can see (with strace) it segfaults while reading from the socket connecting the PDC -
not the first read, but after quite a few gettimeofday()/read() operations.

Will post more info if anyone is interested.
