The fact that the "lambda-list" for u is an atom should signal a program-error.

CLHS flet says:

  lambda-list---a lambda list; for flet and labels, it is an ordinary lambda list; 

and CLHS 3.4.1 says:

The syntax for ordinary lambda lists is as follows:

lambda-list::= (var* 
                [&optional {var | (var [init-form [supplied-p-parameter]])}*] 
                [&rest var] 
                [&key {var | ({var | (keyword-name var)} [init-form [supplied-p-parameter]])}* [&allow-other-keys]] 
                [&aux {var | (var [init-form])}*]) 

so lambda-list for flet and labels cannot be an atom.

And in the case where I found this, u was also a global function, so perhaps this could be tested by the compiler to add a hint in the error message that perhaps the form was intented to be in the body of the flet.

While trying to compile the lisp-only build of Maxima, I encountered a bug which seems to be related to the ARM compiler in CCL. Here are the last lines of the compilation:

This used to work.
