Hi ...
The problem is that the jawk interpreter fails on the attached script -- The script is a mess with cut-n-pastes from old scripts to build a new script.
Jawk just crashes. The same script runs to completion with gnu gawk (latest version). and the code itself is quite old. So if there's a typo, etc gawk should catch it too.
Stack dump...
