Hello.
The compiler always crashes while compiling <mutex> header from Visual Studio 2015 RC1. Bug is absolutely reproducible, it is enough to attempt to compile a .cpp file with single line:
#include <mutex>
Intel(R) C++ Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 15.0.4.221 Build 20150407

mx.cpp
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\mutex(449): internal error: assertion failed at: "shared/cfe/edgcpfe/templates.c", line 28214
Best regards,
Yakov Markovitch
