I've never seen that sort of message here, but I can reproduce the exact 
same behaviour you describe.
What I did:
gnuplot> set term x11
Terminal type set to 'x11'
Options are '0'
gnuplot> f(x) = sin(x)
gnuplot> plot f(x)
gnuplot> set term wxt
Terminal type set to 'wxt'
Options are '0'
gnuplot> replot
Abort(coredump)

So it seems like WX is indeed to blame.

I'm running 8.0-STABLE as of yesterday. gnuplot is at version 4.2.6.

I leave that up to you ;-)
