JWM 2.4.0 crash at startup with floating point exception #537
Description
JWM 2.4.0 immediately crashes back to the console for me with startx. Also see this Arch bug report: https://bugs.archlinux.org/task/73049
The crash occurs in DrawButton. Might be a division by zero if height==0: https://github.com/joewing/jwm/blob/master/src/button.c#L148
JWM 2.3.7 works fine for me...
