           Summary: Copy constructor of SwitchInst does not call
                    SwitchInst::init
           Product: new-bugs
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

        ReportedBy: kevin.streit at googlemail.com

After calling the copy constructor of SwitchInst the newly created SwitchInst
is not fully initialized. In particular the ReservedSpace field is not
initialized which leads to undefined behavior when adding a case to the cloned
switch later.

The same holds for calling SwitchInst::clone_impl() since it just uses the copy
constructor.
