            Bug ID: 24399
           Summary: custom-line-table.test failing on Windows 7 x64 Visual
                    C++
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: yaron.keren at gmail.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

To reproduce I sent the output of llvm-dsymutil to a temporary file.
The output of llvm-dwarfdump.EXE" file "-debug-dump=line" is wrong on the last
line, and thus fails the test.

file:   file format Mach-O 64-bit x86-64
