            Bug ID: 30413
           Summary: Incomplete class information in Ivar objects in
                    libobjc2 code on Linux
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

I recently compiled an Objective-C program on Linux using clang/llvm . I'm
using libobjc2-1.8.1, with llvm 3.7 (clang 3.8). My program links with a shared
library (also written in ObjC), which introspects the instance variables in a
common Configuration class to determine what type each of those variables is.
This has always worked on the Mac with clang and on Linux with gcc. However,
with clang/llvm on Linux, I'm finding that the type introspection fails.

I will attach a sample program that demonstrates the issue.
