I encountered a very similar bug caused by the same bit of code.  In  
my case the issue was the LHS and RHS having different Objective-C  
pointer types (e.g. id and NSString*) which AST is treating as  
equivalent but LLVM regards as incompatible.  Your solution seems  
cleaner than mine (which only handled mismatched pointer types  
correctly), so I'll revert mine before I send updated versions of the  
diff to this list (hopefully soon...).
