------- Additional Comments From marcos.woehrmann at artifex.com  2009-07-19 07:38 -------
The good news is that this is reproducible with 'make debug' and when run under gdb.

The problem appears to be in the command list code (which is reasonable, since all the occurrences of 
the lockup that I've recorded have been with banding turned on).
