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.

Rgds,
Steve

        Cygwin 64-bit and Octave works as expected. I got crashes with fltk

        working fine until I updated -- I can't remember what version of

    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 ?


Regards
Marco
