# REQUIRES: system-darwin

# In this test we have two CUs with conflicting forward declaration
# depending on the CU language (one is C++ and the other is Objective-C++).
# We are then stopped in the C++ CU and try to print the type, at which
# point LLDB will try to make it into an Clang AST node. If LLDB were to
# interpret the type as C++ instead of Objective-C, we'd violate Clang
# invariants and crash.
