(%i1) integrate(cos(x/atan(x)),x);

Maxima encountered a Lisp error:

 Condition in MACSYMA-TOP-LEVEL [or a callee]: INTERNAL-SIMPLE-ERROR: Caught fatal error [memory may be damaged]

Automatically continuing.

Still present in current post-5.46. GCL gives the above error; SBCL gives the slightly more informative

(%i1)  integrate(cos(x/atan(x)),x);

Maxima encountered a Lisp error:

 The value
   0
 is not of type
   LIST

A backtrace shows the error is in the Risch code, specifically RISCHEXPLOG; I don't know if that's a bug in that function, or one of its callers.
