So I'm trying to get the ASDF test suite running on Windows, and tracked this down as one of the failures for CCL (32-bit and 64-bit). (there were 5 failures out of 47 tests, I haven't looked at the rest yet).

This can be replicated as follows (with files from

https://www.dropbox.com/sh/jc2cqwpkp06dupm/7lgyRUdwZ5/cl/tests/simple ):

[below, substitute ".../'" for your actual path to the test files]:

(lisp-implementation-version)

"Version 1.9-r15765 (WindowsX8664)"

(compile-file ".../try1")

(compile-file ".../try2")

(ccl:fasl-concatenate ".../try.wx64fsl" (list ".../try1.wx64fsl"

".../try2.wx64fsl"))

(load ".../try.wx64fsl")

ERROR: Not a FASL file.

Does anyone recognize what might be going on?
