Current results: https://common-lisp.net/project/cl-test-grid/asdf/asdf-diff-56.html
This reports includes only the subset of full diff where new version has failures.

The lisps completed so far:
    ccl-1.10-r16196-f96-linux-x86
    ccl-1.11-r16635-f96-linux-x86
    clisp-2.49-unix-x86
    cmu-snapshot-2016-12__21b_unicode_-linux-x86
    ecl-16.1.2-unknown-linux-x86-bytecode
    ecl-16.1.2-unknown-linux-x86-lisp-to-c
    sbcl-1.3.12-linux-x86

If speak about SBCL results in this report, where previous
 test has CRASH and new one has ffi/ffi-grovel FAIL
-  it's an improvement, because the new version seem to better catch
errors of running external programs.

Why there are so many strange errors on ECL - I can't say now, deeper
analysis is needed. Both tests were run on the same machine.
