Hi, Faré:
Tested on Mac OS X 10.7 with ccl clisp sbcl ecl abcl allegro allegromodern.
For Allegros, I tested with 8.2, 9.0 SMP and 9.0 non-SMP. All of these are 64-bit.
All tests passed.
These were only the noupgrade tests. I don't believe that the upgrading works on ACL 9.0, because the old version of ASDF can't distinguish SMP and non-SMP fasls.
This is probably going to resist any fix other than Franz distributing the latest ASDF. I have corresponded with them, and they will be distributing such a patch soon.
Cheers, r
