Subject: Help: Ap fails for 1.7.2

On several occuassions over the last few months, I've tried to run our application
using the latest CVS snapshot of ruby, but it simply doesn't run.  When I start pairing
down the code to isolate the problem, it vanishes.

$ ruby -r debug -w -d Scalar.rb -p diffusion -v 1
Debug.rb
Emacs support available.

Currently the application works fine with ruby 1.6.7 (2002-03-19) [i686-linux]

Note: I'm using narray-0.5.5

Any pointers as to what to look for or how?

Thanks,
