[Openmcl-devel] Unreliable (load <file>) with MacOS Sierra 10.12.5

Dear Shannon and Ron,

Many thanks for your interest and help. The attached ccl-init.lisp file causes directly the Example 1 problem of my first message. No other file is loaded.

1. Put it in the home directory
2. Start CCL with a double-click
3. After some compiler warnings (cf. initial comment in the file) here's what you get when calling function new:
| Welcome to Clozure Common Lisp Version 1.11-store-r16714  (DarwinX8664)!

| ? (new 'midi-score :name "poipoi")
| > Error: :MODIF is an invalid initarg to INITIALIZE-INSTANCE for #<STANDARD-CLASS MIDI-SCORE>.
| >        Valid initargs: (:NAME :EVENTS :FORMAT :SORTED :LENGTH :FILE).
| > While executing: CCL::CHECK-INITARGS, in process Listener(4).
| > Type cmd-. to abort, cmd-\ for a list of available restarts.
| > Type :? for other options.
4. Open the ccl-init.lisp file and manually evaluate the defclass midi-score... form with Lisp menu > Execute selection or <cmd><E>:
| 1 > 
5. The same call to function new now works OK and returns a midi-score object:
| 1 > (new 'midi-score :name "poipoi")
| #<MIDI-SCORE #x302000EB244D>
| 1 > 

That's it... Many thanks in advance.

This sounds like more of a package problem than a Sierra problem, but without the files in question it’s hard to say. Can you distill down the ccl-init file to a single form that fails as you describe and post it here?

However, I'm switching to CCL to avoid purchasing LW 7.0, aside from the pleasure of going back to an environment similar to MCL, which I used a lot until 2008 on Motorola Macs, and liked very much.
