My best guess is that the problem lies in the code that fails to

As I said before, I'm not sure whether this is really a simplification.  After
all, the *definition* of a^b is %e^(a*log b)

I think you have a small typo there
it should be

the *definition* of a^b is %e^(b*log a)

Since it does not simplify, the call to varselect(kernels ....
continue to loop since %e^(n log(x)) is a kernel.

but a^b is a kernel, too!  I do not understand.
