            Bug ID: 33519
           Summary: llvm-pdbutil crash with bad runtime enum value
           Product: libraries
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: DebugInfo
          Assignee: unassignedbugs at nondot.org
          Reporter: brendandg at nyu.edu
                CC: llvm-bugs at lists.llvm.org

The PDB file found here:

http://panda.moyix.net/~moyix/llvm_pdb_bug/ehiitv.pdb

Causes "llvm-pdbutil pdb2yaml -all" to hit an unreachable switch case. I think
this is similar to Bug 33428 and probably has the same fix.

Stack trace:
