I just compiled the gnuplot pre 3.6 beta 330 source, and found (as for
the standard 3.5 distribution) that gplt_x11 died with a segmentation
fault. The error apparently is caused by the line

    vis = DefaultVisual(dpy,scr);

and goes away if vis is declared locally rather than globally. Maybe
with the ?new compiler? in the ?new release? this arm32 specific
oddity will go away? Diff attached for your amusement.

Cheers,

 Patrick
