## This test checks output of dsymutil for the incorrect DWARF.
## CU1 has a type which references type in CU2. This referenced
## type references the same type in CU1 back. There is a recursive
## dependence between these two types. dsymutil should report a error,
## remove CU1 and CU2, put only CU3 into the output.
