Not a bug, but a misfeature; the code works as intended,
but the intent is questionable.
I looked into this, and there is a loop in MEVAL1 which reevaluates
the name of the function. The code is pretty convoluted -- I'm guessing
it could be simplified a lot.
I don't know the motivation for reevaluating function names.
It would be interesting to disable that somehow to find out what,
if anything, in existing Maxima code (e.g. share) depends on it.
