Thanks for this. My CCL 1.9 is from Mac Homebrew and I keep getting
segfaults:

Welcome to Clozure Common Lisp Version 1.9-r15759  (DarwinX8664)!
? (require :objc-support)
:OBJC-SUPPORT
("OBJC-PACKAGE" "SEQUENCE-UTILS" "NAME-TRANSLATION" "OBJC-CLOS" "OBJC-RUNTIME" "BRIDGE" "OBJC-SUPPORT")
? (objc:@selector #/addObject:forKey:)
