It is the extension for big integers as argument of the log function in
the routine $float, which causes the problem. Negative integers have to
be handled more special. Now we get a CL complex:
(%i2) float(log(-1));
Maxima encountered a Lisp error:
Argument X is not a REAL: #C(0.0 3.141592653589793)
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.
