[MacRuby-devel] Problems with return code from sheet (possible regression)

[Michael Winterstein]

I seem to have run into nearly the same problem that I had a while  
back, in this ticket:
http://www.macruby.org/trac/ticket/221

I haven't filed it yet this time since last time it turned out to be  
already fixed, but I'm not certain that's the case now.  At any rate,  
it's being handled by different functions.
The same thing is happening - the return code being passed to my  
delegate (from [NSApplication endSheet:returnCode]) isn't being  
treated as the NSInteger it ought to be.  At least I think so.  Here's  
the trace, and you can see that the value 1(NSOKButton) is being  
treated as id, causing problems (0/NSCancelButton doesn't crash as  
it's a special case) :

Program received signal:  “EXC_BAD_ACCESS”.

#11 0x00007fff81e45acc in -[NSApplication run] ()
#12 0x00007fff81e3e798 in NSApplicationMain ()

Attached are a few files as a test case, an NSWindowController  
subclass and MainMenu.nib that can be dropped into a  new project to  
check this if anyone wants to.  I recall when I first had this problem  
that I could see what the change was, but unfortunately I've forgotten  
that now.
