      Just a blind guess:  Does setting "level 1" fix the crash?  Unspecified

      level means level 0, which is invalid.
     
     
Nope sorry, it´s not that easy. I´ve always put a level > 0 to the
wands. I just forgot to mention that in the description above.

That bug is really weird, and it applies only to wands and staffs.
It doesn´t apply to rods for example, although wands and rods are
treated with one and the same function most of the time.
Moreover, it doesn´t seem like there would be any difference between
standard and no-standard wand spells (except that the former cause
crashes and the latter don´t).
And finally, the error message "Floating exception":
That sounds like a buffer overflow occured. And all this caused by a
left-click.

It´s a miracle...
