   1 ## This test checks debug info for the case when one compilation unit
   2 ## contains a definition of a type and another compilation unit
   3 ## contains a definition of the same type. When --garbage-collection
   4 ## is enabled the result should contain the original definition in CU1
   5 ## and the definition from CU2 should have been removed.
