Hi.

I recently "found" clog and love what I see (as an old Delhpi guy what is not to like?). However, when I attempt to build the system it crashes in 3BMD by looks... (backtrace is below)

This is against SBCL 2.1.9 on OSX 11.6.2 (M1) using a git-clone of the latest CLOG sources (18 hours ago is the latest).

Any ideas on how to get this subsystem error?

TIA
