            Bug ID: 41880
           Summary: ~RTDyldMemoryManager should call deregisterEHFrames
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: OrcJIT
          Assignee: unassignedbugs at nondot.org
          Reporter: tneumann at users.sourceforge.net

The class RTDyldMemoryManager does not de-register the exception handling
frames automatically when the memory manager is destroyed. This leads to
crashes in C++ exception handling when an exception is thrown after an orc JIT
instance is destroyed.

The problem can be fixed trivially by calling deregisterEHFrames from the
destructor of RTDyldMemoryManager. This is a regression introduced by llvm 8,
and is probably an oversight caused by code movement.
