With Allegro 8.1 in both ANSI and modern (case-sensitive) modes, two of the tests fail:
test-retry-loading-component-1.script test-utilities.script
I have not yet had a chance to debug this.
This message may bounce from asdf-devel, since I have had to send it from gmail (linux box doesn't have configured email).
I have not yet tested with CCL or ABCL, the other two CL implementations available to me.
Tests pass on SBCL, which I presume you have already checked.
Best, r
