Ok, I Have had a quick look at this, at it segv here inside
wsize with and without libefence.

However this is a programming bug in it, in that it is really
not safe to call wresize from inside a signal handler. 

That's not whats causing the segv, I'm seeing here as I applied
this patch (attached) to fix it - but it hasn't made any difference
to the programs behaviour.

(I've been testing here with both 5.0 and 5.2.20020112a).

TTFN.
