InitDB: Bad system call

Hello,

i've just compiled a new Jail at my FreeBDS 7.0-STABLE machine and
trying to get PostgreSQL 9.0 Beta 4 running. Compiling etc works fine.

But when i call the initdb, i get "Bad System Call" messages. Here is
the output:

$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data -d

initdb: removing contents of data directory "/usr/local/pgsql/data"

There is no further message in /var/log/messages.

First i believed this is an error relating to SYSVSHM-, SYSVSEM-,
SYSVMSG-options or User-Id
(http://www.freebsddiary.org/jail-multiple.php). But the postgres-user
has a user-id which is not used by other postgres-instances in other
jails. And the other options are enabled in the root-instance.

I also tried to build postgres from a fresh portstree, to make sure,
that i have nothing miss-"./configure"d, but there are the same problems.

I have no clue, what the problem is. Any hints?

Thanks,
Torsten
