Good day Richard,
Then, let's produce the complex solutions. End of story.
For exp(a * x) = c * exp(b * x), let's printout all possible solutions
if finding only the real solutions (like some other tools do) is a bad idea.
But then, if in turn, I don't want people to use that excuse later to
say "wait! maxima can't solve with exp because exp is not one-to-one!".
