emacs-28.2; win 11

$ emacs -Q 

1. If I use most-positive-fixnum:

   (lossage-size most-positive-fixnum) 

   Emacs will emitted: Value must be >= 100 in echo area.

2. If I use a modest number:

   (lossage-size (/ most-positive-fixnum 10)) 

   Emacs will crash immediately.

I just want to use most-positive-fixnum to indicate that I won't limit the size of lossage.
