[armedbear-devel] how to debug?

I've packaged up a reduced system.
http://ashby.csail.mit.edu/abcl-obo.tgz

Unpack, cd into the unpack directory, and execute bin/abcl
Once loaded:

(setq obo (make-instance 'obo :path "~/Desktop/abcl-obo/unit.obo")) ;;
adjust to where you unpacked it

#<OBO {E71A6D}>

CL-USER(8): (read-obo obo)

Debugger invoked on condition of type JAVA-EXCEPTION:
  Java exception 'SchemeException: ERROR:
NO INSTANCE METHOD OF TYPE

  (.matcher org.armedbear.lisp.Cons ...)'.
Restarts:
  0: TOP-LEVEL Return to top level.

If you evaluate the read-obo function and try again it will succeed,
demonstrating that the compiled version doesn't work as compared to
the evaluated version.

Similarly if you disable the inline lambda expansion and recompile it
will run without error.
