Folks;
Tiger 10.4.11 -- XC 2.4.1
I'm baffled by an IB error.
Reasonable development has been on-going.
Pretty stringent Build Rules and no errors or warnings.
I decide to do a clean build, torch the app's prefs file and the
CoreData store.
I want to focus on the initial installation phase of the app...
To my great surprise I cannot now get the app to launch successfully.
It ran fine 15 minutes beforehand...
Regardless of whether I 'Run' or 'Debug' I get the exact same result:
I get all the way through the appDelegate's -awakeFromNib and the
pref window opens (as I expect on first launch) but the debugger
kicks in with the following:
#0 0x90a594c7 in objc_msgSend
#1 0xbffff7b8 in ??
#2 0x932849d8 in loadNib
#3 0x932843d9 in +[NSBundle(NSNibLoading)
_loadNibFile:nameTable:withZone:ownerBundle:]
#4 0x9328403a in +[NSBundle(NSNibLoading)
loadNibFile:externalNameTable:withZone:]
#5 0x93283f7c in +[NSBundle(NSNibLoading) loadNibNamed:owner:]
#6 0x93283cc3 in NSApplicationMain
#7 0x00405ffc in main at main.m:18
In the Console I see:
....Normal log messages that I generate and expect (including the
'end-of-awake-from-nib' stamp)
Program received signal: "EXC_BAD_ACCESS".
I have the [NSException raise] as a Global breakpoint but it doesn't
fire.
Using the po command I can tell that MainMenu is the nib involved;
the prefs window is in a separate nib...
How do I track this down?
Steve
