            Bug ID: 26298
           Summary: msvc exceptions crash clang.exe
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

I compiled clang in visual studio 2013 myself (from git), however even when
running directly from visual studio it won't resolve function names. Same
behavior with Debug and RelWithDebInfo. If you could tell me how to do that I
could possibly provide more info.

Anyway I followed the how-to-submit-bugs guide and used multidelta (wow!!! I'm
in love). It reduced the file in question to:

template <class _E> void *__GetExceptionInfo(_E);


This line alone crashes clang.exe. It is in C:\Program Files (x86)\Microsoft
Visual Studio 12.0\VC\include\exception

I know exceptions are not fully supported - but this is a rather severe
limitation if I cannot include the file at all. Also some other bug report
comments suggest that it should actually work by now:

command: clang -v -target i686-pc-windows-msvc -O0 crash.cpp
version: from git so I'm not sure whether it's "258628". The full message
reads: Improving documentation for the isMoveAssignmentOperator AST matcher.
Patch by Jonathan Coe.
