Other than the fact you're not checking for NULL when using CFRelease(). I've learned to not trust any CF API to never return NULL except CFSTR() (and I'm even hesitant on that).

But is this happening in another thread? It looks like this is a cocoa application and if you're doing this in another thread, you need to wrap the insides of the function with an NSAutoreleasePool, much like almost anything at Jack in the Box.

I've got some code calling CreateStandardAlert/RunStandardAlert that is leaking a whole truck load of memory.

The code is as follows:
void shareware_annoy(void) { AlertStdCFStringAlertParamRec paramRec; OSStatus err; DialogRef alert; DialogItemIndex itemHit; CFStringRef def, can, oth, tit, det;

// Load strings def = CFCopyLocalizedStringFromTable(CFSTR("Yes Please"), CFSTR("Shareware"), "SW_DEFAULT"); can = CFCopyLocalizedStringFromTable(CFSTR("Maybe Later"), CFSTR("Shareware"), "SW_CANCEL"); oth = CFCopyLocalizedStringFromTable(CFSTR("Reinstall"), CFSTR("Shareware"), "SW_OTHER"); tit = CFCopyLocalizedStringFromTable(CFSTR("Brain Box is a shareware product. Would you like to register now?"), CFSTR("Shareware"), "SW_TITLE"); det = CFCopyLocalizedStringFromTable(CFSTR("This message appears on program launch. It can be removed permanently by paying the shareware fee instantly online via credit card."), CFSTR("Shareware"), "SW_DETAIL");

// Get defaults GetStandardAlertDefaultParams(&paramRec, kStdCFStringAlertVersionOne); paramRec.defaultText = def; paramRec.cancelText = can; paramRec.otherText = oth; err = CreateStandardAlert(kAlertCautionAlert, tit, det, &paramRec, &alert);
	// Release all the strings now, since they'll be retained above.
	CFRelease(def);
	CFRelease(can);
	CFRelease(oth);
	CFRelease(tit);
	CFRelease(det);
	// Run the alert
	if (err == noErr)
	{
		err = RunStandardAlert(alert, NULL, &itemHit);
	}
}
Has anyone seen this one before? What am I doing wrong?
Many thanks,
