[asdf-devel] Obscure A-B-L bug?

[Daniel Herring]

Hi,

The following is representative of an obscure bug I'm trying to resolve 
(without direct access to the computer).  It affects A-B-L 0.3.8 and a 
recent release of ASDF, but I don't see any relevant changes to either 
project in the past couple years.

To set up this example,
# cd /path/to/.asdf
# ln -s ../asdf-binary-locations/asdf-binary-locations.asd .

Then under LispWorks on a PPC mac,

CL-USER > (push #P"/path/to/.asdf/" asdf:*central-registry*)
CL-USER > (asdf:operate 'asdf:load-op :asdf-binary-locations)
; loading system definition from
; /path/to/.asdf/asdf-binary-locations.asd into
; #<The ASDF0 package, 0/16 internal, 0/16 external>
; Loading text file /path/to/.asdf/asdf-binary-locations.asd
; registering #<SYSTEM ASDF-BINARY-LOCATIONS 200B9373> as ASDF-BINARY-LOCATIONS
Error: The file #P"/path/to/.asdf/dev/main.lisp" does not exist.


ASDF is clearly resolving the symlink to read A-B-L.asd; but its using the 
wrong path to load the source files.  Is the custom load-op for 
load-only-cl-source-file somehow skipping the normal truename/path merging 
process?  Any other ideas or things to look for?

Thanks,
Daniel
