Test case
When parsing the very simple following code using clang, it asserts (and so
abort) instead of just emitting a diagnostic.
------- attr.m
@interface Foo { id ivar __weak; }
@end
------------
% clang --version
clang version 2.9 (trunk 127155)
Target: x86_64-apple-darwin10
Thread model: posix
% clang -c attr.m
attr.m:2:26: error: multiple garbage collection attributes specified for type
@interface Foo { id ivar __weak; }
^
<built-in>:140:31: note: instantiated from:
#define __weak __attribute__((objc_gc(weak)))
^
