Hello Simon and Laurant,

Now I don't know anything about this issue specifically, but it's customary
to provide some extra information when reporting bugs, what OS and
OS version are you using for example ?

Did you download a Linux-distribution binary ? What kernel version are
you using ?

Or did you build from an updated BSD-ports. Did you do your own build ?
If so, what compiler did you use ? And so on.

Some information would be better then no information. :-)

Just so you know.

Have a nice day,
     Leen.
