My old C debugging memories are slowly returning.
I recompiled with CHUCK_DEBUG, and still, this looks really bad:
Program received signal SIGSEGV, Segmentation fault.

Hey Ken, Yikes, sorry to hear that. Could you provide a stack trace of this? That would be most helpful in figuring out the problem. Im not sure if you're handy with gdb, but the easiest way to do it is like this:
$ gdb chuck (gdb) run -v5 cw.ck ... (crash happens) ... (gdb) backtrace ... (stack trace printed here) ...
Copying all of the output of that gdb session (including the chuck log output) will be very helpful as that typically specifies exactly where the crash is occurring.
It would also be helpful if you could provide the text of cw.ck, if you don't mind. It can be assumed that cw.ck doesn't crash ChucK on other machines, correct?

Alas, I am dead in the ChucK waters.
Just got a new Core 2 Duo laptop. Built ChucK 1.2.0.8 for linux- jack. Planned to use this machine for ChucK experimentation and live performance.
And then:
$ chuck cw.ck Segmentation fault
Gah!

Sad. No ChucK for me! This is with the stock 1.2.0.8
