I suspect the reason the packaged gnuplot crashes and the built one
doesn't is your "unofficial" wx 2.9 packages. Can you please run

 ldd ./gnuplot | grep wx

on the gnuplot binaries that you see crashing? I suspect you'll see wx
2.9 on those. If that's the case, it'll be interesting to see you
rebuild gnuplot with wx 2.8, and see if that crashes or not.

This may still be a bug in gnuplot, but it'd be great if you could run
this test so that the cause can be narrowed down.
