[xslt] Bug (?) in attribute set resolver?

["Jonathan S. Shapiro" <shap eros-os com>]

I have a very small XHTML input file, and a transformer script that
wants to re-emit it as HTML with only trivial changes. It takes
*forever* (and used to be quite fast) and generates errors.

When run with -v, I see parsing complete successfully, followed by:

  Resolving attribute sets references
  error: Operation in progress
  error: Operation in progress

Is there some way to get more verbose output in this phase so that I can
figure out (a) why this processing is taking so long on such a small
input, and (b) why the errors are occurring?

Or more generally, how should I go about attempting to debug this?

Thanks,


Jonathan
