            Bug ID: 22035
           Summary: Crash when build iostream.cpp from libc++ on Windows
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: abyss.7 at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

Initially, I try to build libc++ on Windows. But it doesn't show any
stacktrace, so I took generated cpp+sh and rerun on Linux to get stacktrace.
The only difference in a command-line is the path to clang++.

Clang++ crashes with a following output:
