Hi, I'm running into an odd crasher on PowerPC machines. I have a custom NSView called TYCurrentDayView that draws an nsmutableattributedstring on top of a gradient. On a few instances, I will receive the following crash:
Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x000000000000001f Crashed Thread: 0 Application Specific Information: objc[24283]: garbage collection is ON Thread 0 Crashed: 0 libobjc.A.dylib 0xfffeff18 objc_msgSend_rtp + 24 1 com.apple.AppKit 0x93d33c3c -[NSATSGlyphStorage setGlyphRange:characterRange:] + 2424 2 com.apple.AppKit 0x93d331b4 -[NSATSTypesetter _ctTypesetter] + 276 3 com.apple.AppKit 0x93d324f0 -[NSATSLineFragment layoutForStartingGlyphAtIndex:characterIndex:minPosition:maxPosition:lineFragmentRect:] + 92 4 com.apple.AppKit 0x93d316d0 -[NSATSTypesetter _layoutLineFragmentStartingWithGlyphAtIndex:characterIndex:atPoint:renderingContext:] + 1916 5 com.apple.AppKit 0x93d30b18 -[NSSingleLineTypesetter createRenderingContextForCharacterRange:typesetterBehavior:usesScreenFonts:hasStrongRight:maximumWidth:] + 388 6 com.apple.AppKit 0x93d81b38 __NSCreateRenderingContextForAttributedString + 288 7 com.apple.AppKit 0x93d25680 -[NSAttributedString(NSExtendedStringDrawing) boundingRectWithSize:options:] + 1052 8 com.apple.AppKit 0x93df067c -[NSAttributedString(NSStringDrawing) size] + 52 9 com.secondgear.today 0x00008054 -[TYCurrentDayView drawRect:] + 900 10 com.apple.AppKit 0x93dad044 -[NSView _drawRect:clip:] + 2908 11 com.apple.AppKit 0x93dac02c -[NSView _recursiveDisplayAllDirtyWithLockFocus:visRect:] + 844 12 com.apple.AppKit 0x93dac2d0 -[NSView _recursiveDisplayAllDirtyWithLockFocus:visRect:] + 1520 (Full Trace at http://secondgearllc.com/attachments/42208crasher.txt) The code itself that looks to be causing the issue is: NSMutableAttributedString *todaysDate = [[NSMutableAttributedString alloc] init]; NSMutableAttributedString *datePrefix = [[NSMutableAttributedString alloc] initWithString:NSLocalizedString(@"Today is ", @"Today Is String")]; NSMutableAttributedString *actualDate = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@", [dateFormatter stringFromDate:self.currentDay]]]; [todaysDate appendAttributedString:datePrefix]; [todaysDate appendAttributedString:actualDate]; NSRange fullDateRange = NSMakeRange(0, todaysDate.length); NSRange dateOnlyRange = NSMakeRange(9, todaysDate.length-datePrefix.length); // The amount of chars in "Today is " [todaysDate beginEditing]; [todaysDate addAttribute:NSFontAttributeName value:[NSFont fontWithName:@"Lucida Grande" size:16.0] range:fullDateRange]; [todaysDate addAttribute:NSFontAttributeName value:[NSFont fontWithName:@"Lucida Grande Bold" size:16.0] range:dateOnlyRange]; [todaysDate addAttribute:NSForegroundColorAttributeName value:[NSColor whiteColor] range:fullDateRange]; [todaysDate addAttribute:NSKernAttributeName value:[NSNumber numberWithFloat:0.5] range:fullDateRange]; [todaysDate endEditing]; I've never been able to reproduce it on any Intel machines, but it happens about 10-20% of the time on PowerPC Macs. Any help would be appreciated. - Justin Williams [EMAIL PROTECTED] http://secondgearllc.com/ - Check out Today: iCal's new best friend <http://secondgearllc.com/today/>- _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
