WindowMaker crashes regularly and restarts itself (every few hours)
Had the same issue on 9.3, but 10.0 shows it still.

Visible effect is a flicker and that all your Windows suddenly appear on a
single desktop only. I haven't correleated it to a specific action, but it
usually happens after some action on my side (Window change etc.) 

The kernel log shows:

wmaker[6298] general protection rip:465b3a rsp:7fffffc9f040 error:0

The RIP is in WMColorGC and and the crash happens because

205     GC
206     WMColorGC(WMColor *color)
207     {
208         if (!color->gc) {
209             XGCValues gcv;
210             WMScreen *scr = color->screen;
211
(gdb) 
212             gcv.foreground = color->color.pixel;
213             gcv.graphics_exposures = False;
214             color->gc = XCreateGC(scr->display, scr->rcontext->drawable,
                                                    ^^^^^^^^^^^^^
215                                   GCForeground|GCGraphicsExposures, &gcv);
216         }
217
218         return color->gc;
219     }

scr->rcontext contains a bogus pointer (not NULL, but some garbage with
bits set in the uppermost 8 bits, which is not valid in x86-64)
