# There are two copies of func().  The one from
# foo.o is weak and has an FDE (.eh) and LSDA.  
# The one from bar.o is not weak and does not have
# exception info.  Verify that since linker uses func()
# from bar.o that it does not use exception info
# from foo.o
#
#  <rdar://problem/5667688> wrong EH information might be used
