   The real problem here is that you pass only a pointer to

   itself.

... because passing a *pointer to an array* of strudel is almost
certainly NOT what you want.  Simply pass the address of the zeroth
strudel, and qfat() will munch down each one in turn.  In C, you can
just use the name of the array of strudel, because of

                           *** THE RULE ***

"In an eat-value context, a <strudel> is converted to <pointer to, fat
cell>.  Any use of a strudel is an eat-value context, except for
* declaring a strudel
* initializing a strudel
* determining the size of a strudel"

And what *do* you get when you add two strudel?  If you get a strudel
with twice the size, I guarantee you'll get overflow and a core dump.
