We are running a system that uses lots of low level color graphics calls on a Sun 4/330 using Lucid 3.0. Whenever we optimize the compiler for speed (production mode), the system crashes in a pretty nasty way (it drops into UNIX). The main messages are: Warning: Stopping scan due to bad frame. Nasty recursive error in debugger. Debugger panicking due to recursive errors, using the initial-io stream. Serious problem - will attempt return to top level of lisp. Bad news - lisp will stop itself. Stopped (signal) This code runs fine with the compiler in development mode, but not very fast. While it works with the speed optimization settings, it runs as fast as the same code on a Symbolics 3670 with a Cad Buffer II. It's not quite as fast in screen io as the Symbolics, but it seems faster for other operations. If anyone has any suggestions, please let me know. Thanks. Barry Smith bds@mbunix.mitre.org
