I’m running Mojave 10.14.2 and SBCL 1.5.0. When I try to load CFFI, I get this error:

* (ql:quickload :cffi) To load "cffi": Load 1 ASDF system: cffi ; Loading "cffi" [package cffi-utils].............................. [package cffi-features]........................... [package cffi-sys]....; ; caught ERROR: ; READ error during COMPILE-FILE: ; ; Lock on package SB-ALIEN violated when interning SHARED-OBJECT-FILE while in ; package CFFI-SYS. ; See also: ; The SBCL Manual, Node "Package Locks" ; ; (in form starting at line: 306, column: 0, position: 10629)

Then I’m dumped into the debugger. The same thing occurs using (asdf:load-system :cffi). I’ve cleared ~/.cache/common-lisp, but no joy. Any thoughts appreciated.

Thanks,

Patrick
