I will. I can also try with using the local filesystem instead of the "weird" shared filesystem from the virtual host. Will do the 3.1.0.27 with the current setup first, and try that next. Sticking with Linux only until things settle out then will revisit the Windows testing.
Indeed when running with local filesystem in the Linux VM, all 48 tests pass on clisp.
The failures for 3.1.0.27 are for the mounted filesystem and can be seen here:

Starting Windows tests on local Windows filesystem in the VM now...
