/* This test checks that local aliases behave sanely. This is necessary for code correctness

This test expose weird behavior of AIX's .set pseudo-op where the global symbol is created,

but all uses of the alias are syntactically replaced by uses of the target. This means that

both counters are increased to 2. */
