Error in Intel C++ compiler 16.0 in enumeration checking

I have a piece of code that successfully compiled by Xcode native complete in c++14 mode. The attempt to compile it with icc with -std=c++14 give the following error:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Security.framework/Headers/CSCommon.h(203): error: enumeration value is outside the range of its underlying type ("unsigned int")

      kSecCSConsiderExpiration = 1 << 31,        /* consider expired certificates invalid */

Is it normal? 1<< 31 is 0x80000000 and it a prefect unsigned int value.

Did you mean to type 1U << 31 ?

It's unusual but not unheard of for icc to exhibit more thorough checking than clang or gcc.

I have show you line from the Apple framework header, so I don`t know what the means there. What the way of solving this problem? I can`t correct standard headers... In any way 1 << 31 is inside int and unsigned int, why does icc get error here?

HI Mikhail,
Can you attach a test reproducer (preferably a preprocessed file compiled with -P option that generates the .i file) so I can investigate the issue?
Thanks,
Kittur

Hi Kittur Ganesh,

As you requested .cpp and .i files is in attachment. One remark: I try to use icc version 16.0.1 20151020, because 16.0.2 20160204 could not compile std::function<> template at all. In update2 there is no problem with the enum itself.

Maybe you know when to expect update 3 of icc version 16?

Mikhail.

Hi Mikhail,
I couldn't reproduce the issue with your attachment. Also, the cpp file only has the include line and main function which is empty. Unless I can reproduce the issue I can't file with the developers :-(

Good to know you don't have any issue with update 2 on the enum itself.  Well, the update 3 should be released as well soon but I don't have the correct schedule with me. I'll keep you updated as soon as the release is out?
Thanks,
Kittur

BTW, the workaround is to not use C++11 for now until the release with the fix is out, appreciate much.
