[Openmcl-devel] 32 bit COCOA problem with Mac

I looked at it for a few minutes.

If you put (#_NSLog #@"pane = %@" :id pane) at the top of the function gui::make-scrolling-textview-for-pane and then do (require 'cocoa), it will crash into the lisp kernel debugger there.  You can then start lldb and attach to the crashed ccl by typing "attach 123" where the "123" is the process ID of the crashed lisp.  The kernel debugger helpfully prints the pid in the prompt.  That is, in

[5887] Clozure CL kernel debugger:

the 5887 is the pid of the lisp.  So, after typing "attach 5887", type "cont", and then type "p" at the kernel debugger prompt.  The lldb will then catch the exception that caused the crash, and you can type "bt" to get a backtrace, and use other debugger commands at that point.

After attaching lldb, it shows:

* thread #1: tid = 0x2d4716, 0x94dabcac libobjc.A.dylib`objc_msgSend + 28, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x2)
  * frame #0: 0x94dabcac libobjc.A.dylib`objc_msgSend + 28
    frame #1: 0x9532f9e8 Foundation`_NSDescriptionWithStringProxyFunc + 49
    frame #2: 0x9cee5442 CoreFoundation`__CFStringAppendFormatCore + 10066
    frame #3: 0x9cee2cc7 CoreFoundation`_CFStringCreateWithFormatAndArgumentsAux2 + 247
    frame #4: 0x9cf8339c CoreFoundation`_CFLogvEx2 + 124
    frame #5: 0x9cf9da80 CoreFoundation`_CFLogvEx3 + 144
    frame #6: 0x953d689e Foundation`_NSLogv + 171
    frame #7: 0x953bfa32 Foundation`NSLog + 26

So, it appears to me that it died when it was trying to do the equivalent of [pane description] in order to print it out.  That leads me to suspect that pane is not a valid Objective-C object at that point, but I don't know why.

Obviously, it would be nice if this worked. At some point, I hope that I will be able to spend the time to debug and fix it, but I'd certainly love to get a patch from someone who is interested in figuring it out sooner.
