Unfortunately I got a core dump from cwtm (compiled Dec 17).

Core was generated by `ctwm'.
Program terminated with signal SIGSEGV, Segmentation fault.

That value for cmap looks bogus...

(gdb) print *cwin
$2 = {w = 79691778, colormap = 0x101000100000001, visibility = 2047083, 
  refcnt = 1}

That 'w' value does seem to be a valid window of mpv, the media player.
I was just doing something with it when ctwm crashed (I think making it
fullscreen or something).

(gdb) print *vevent
value has been optimized out

I haven't been able yet to dig further into this.
