            Bug ID: 34340
           Summary: __xray_function_address(...) returns the first address
                    instead of the function's address
           Product: XRay
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Runtime
          Assignee: dberris at google.com
          Reporter: dberris at google.com
                CC: llvm-bugs at lists.llvm.org

XRay is erroneously returning the address of the instrumentation sled instead
of the address of the function in the instrumentation map. This may lead to
issues attempting to resolve symbols against the sled's address because this
may not correspond to the actual function's start address at runtime.
