Andreas already added DestroyMagickWand() calls that imply clearing, and
I locally added MagickWandTerminus() calls. Right now, I presume the
leak is not on the IM side.
Your patch in the other mail (I'll try it later) seems to support that
guess.

No, always.

I tested with PNG and TIF, and both have the problem.
