there are more details in my mail to sbcl-devel, but this warning
comes from a nested compilation initiated by some generic method
internals. most probably sbcl fails to provide enough info, but here
is the content of the .sbcl-warnings file for the initiated eyes:
((SB-C::*UNDEFINED-WARNINGS*
(:VARIABLE HU.DWIM.PEREC::INSTANCE 1
(:ENCLOSING-SOURCE NIL :SOURCE NIL :ORIGINAL-SOURCE "
(SB-MOP:SLOT-VALUE-USING-CLASS # HU.DWIM.PEREC::INSTANCE ...)"
:CONTEXT
((LAMBDA (SB-PCL::.METHOD-ARGS. SB-PCL::.NEXT-METHODS.)))
:FILE-NAME :LISP :FILE-POSITION 0 :ORIGINAL-SOURCE-PATH (1 2 3 2 4 2
0)))))
to sum it up, it's a warning signaled by sbcl due to a bug, and
doesn't contain source location. so, i think it's something we can
safely ignore as a nasty corner case...
