[Pyobjc-dev] Confusing crash that's fixed by adding NSBeep()

[Scott H. <sco...@gm...>]

I've got this obj-c object in a simple demo program:


@implementation junker
-(id) init
{
    [super init];
    NSLog(@"initing");
    [self action];
    return self;
}
-(void) action
{
    NSLog(@"junk");
    //NSBeep();
}
@end

I call it from Python in my App delegate like this:

from Foundation import *
from AppKit import *

class PyObjCTestAppDelegate(NSObject):
    def applicationDidFinishLaunching_(self, sender):
        NSLog("Application did finish launching.")
        self.a=junker.alloc().init()

    def awakeFromNib(self):
        NSLog("Awoke from NIB")
		
    @objc.IBAction
    def buttonPress_(self, sender):
        NSLog("Button pressed!")
        self.a.action()

The funny thing is that the program crashes when I press the button that calls buttonPress iff NSBeep is commented out, but runs fine if the NSBeep is uncommented. Strange.

Here's the console output:

Any ideas?
