Marco -- I've just tried that, rolling dri-drivers back to 11.0.9-1 and it works.
Thank you for such rapid responses... hope this helps the developers/package maintainers.

Marco: I confirm that was broken for 32-bit. I've just installed Cygwin 64-bit and Octave works as expected. I got crashes with fltk and qt graphic toolkits, but I admit I didn't try gnuplot. All was working fine until I updated -- I can't remember what version of Octave I was running but 4.0.0 sounds about right. Regards, Steve I guess Tatsuro was thinking to revert only cygwin package to 2.4.1. I just tried and it makes no difference. the segfault seems in the X libraries #1 0x43934357 in gallium_dri!__driDriverGetExtensions_swrast () from E:/cygwin/lib/dri/swrast_dri.so Reverting dri-drivers to 11.0.9-1 seems to solve the issue. Yaakov, can you give a check ?
