Does firdes.band_pass *always* produce a working filter?

I assume that it uses the Remez exchange algorithm to do its work.  What
happens if you ask for
  for a filter that can't be realized?

Right now, I have a bunch of filters that are roughly 200Hz wide, and
I'd asked firdes.band_pass to
  produce filters that had 5Hz transition bands.  The result was a CPU
hog, so I backed-off to transition
  bands that are roughly 20Hz wide.  Less CPU usage now.  Is there any
way to tell if firdes.band_pass produced
  a correctly "converged" filter?
