Comments: The error can be reproduced when quickloading any project which needs to be fetched remotely and unpacked. I have tested on SBCL 1.4.1 and encountered no errors. I do not know if the error is in LispWorks 7.1's compiler or in how quicklisp optimizes deflation specifically for LispWorks using their unsafe int32 API.

Workaround: Use SBCL to quickload libraries initially and then they can be quickloaded by LispWorks 7.1. Not a great solution, but it works.
