I'm running a CL program on the 2004-04 snapshot.
My program uses the screamer library in clocc.
I compiled my program with
(declaim (optimize (speed 1) (debug 3) (safety 2)))
AFAICT, screamer itself doesn't seem to have any optimization
declarations.
It runs for a couple minutes, then comes back with:
Unhandled debug-condition:
No debugging information available.
[Condition of type DEBUG-INTERNALS:UNHANDLED-CONDITION]
Restarts:
0: [ABORT] Abort handling SLIME request.
1: Return to Top-Level.
Debug (type H for help)

Any ideas how I can deal with this? I wouldn't be surprised if
there's a bug in my program, but I'm not sure how to find whatever
this is. Is this a CMUCL or a SLIME problem?
For what it's worth, my startup message and features list are:
