[cfe-dev] [Clang 3.0] Inconsistent warnings about assignment in a condition

Hi,
I can't find a way to make Clang _always_ trigger warnings about
assignment inside a condition. When I create a new project (Mac or
iOS) in Xcode 4.3.1 and compile it, the following code does not
trigger any warnings:
- (id)init
{
if (self = [super init]) {
// ...
}
return self;
}
In my current project (which has been created in Xcode 4.2), this code
triggers the proper warning "Using the result of an assignment as a
condition without parentheses".
The following code triggers the warning as well (which is expected):
NSUInteger uid = 10;
if (uid = 11) {
// ...
}
BUT, in the same project I don't get any warnings in the following case:
if (self.uid = 11) {
// ...
}
Is this behavior expected? Which flag should I use in order for the
compiler to catch this case too?
Thanks!
(I'm not on the list, please /cc)
