[cfe-dev] Building Xerces 3.1.2 with cl-clang in VS2010/2013 is very very slow and fails

[Dennis Luehring]

Versions:
   Xerces C++ 3.1.2 release (svn co 
https://svn.apache.org/repos/asf/xerces/c/tags/Xerces-C_3_1_2)
   LLVM-3.7.0-r239299-win32.exe (from 9.6.2015-13:30)
   VS2013 (Update 4)

Bulding Debug/Release:
c:\temp\Xerces-C_3_1_2\projects\Win32\VC12\xerces-all\xerces-all.sln

gives:

Output:
1>  PHI node entries do not match predecessors!
1>    %cast.result74 = phi %"class.xercesc_3_1::DOMNode"* [ %9, 
%cast.notnull.71 ], [ null, %entry ], !dbg !957

1>CL : fatal error : error in backend: Broken function found,

1>  clang version 3.7.0 (trunk)

http://llvm.org/bugs/ and include the crash backtrace, preprocessed 
source, and associated run script.
1>  clang-cl.exe: note: diagnostic msg:

Error-List:
Error    190    error : error in backend: Broken function found, 
compilation aborted! 
c:\temp\Xerces-C_3_1_2\projects\Win32\VC12\xerces-all\XercesLib\CL
Error    191    error : clang frontend command failed with exit code 70 
(use -v to see invocation) 
c:\temp\Xerces-C_3_1_2\projects\Win32\VC12\xerces-all\XercesLib\clang-cl.exe

the microsoft cl-VS2010/VS2013 (without threaded compile and /MP) 
compiles in this szenario serveral (5 or more) times faster then cl-clang

anything (how to use the -v switch?) i can do to reduce the bug 
information further?
