           Summary: Assertion `use_empty() && "Uses remain when a value is
                    destroyed!"
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Core LLVM classes
        AssignedTo: unassignedbugs at nondot.org

That aasertion on Value::~Value fails when executing examples/Fibonacci.

Those debug messages are also shown, which comes from the same place:

Use still stuck around after Def is destroyed:  %arg1 = sub i32 %AnArg, 2
Use still stuck around after Def is destroyed:  %cond = icmp sle i32 %AnArg, 2

A fix for PR 8068, which reports the same assertion on clang, was just
committed on r113042. The problem with Fibonacci was unaffected by that fix.
