This is a post from Maxima mail list and answer from R. Fateman:

http://thread.gmane.org/gmane.comp.mathematics.maxima.general/24555

Looks like a bug, perhaps in the definition or use of findexpon

    Not present in current (post-5.30) version. Probably fixed by commit 82ced588a234, although I didn't verify that. Closing this report since bug is not present.
