            Bug ID: 18553
           Summary: WinCOFFObjectWriter crash
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

    Classification: Unclassified

Tested with r199548. No crash when emitting assembly, only when emitting obj.

llc -filetype=obj HelloWorld.ll

Unfortunately I was unable to reduce testcase with bugpoint - it tried to
remove thousands of instructions one by one during several hours...

0.      Program arguments: llc -filetype=obj HelloWorld.ll
