Description
Intel Issue ID: 6000117300
When compiling Qt 5.6 or 5.7 with ICC 15.x or 16.0 on OS X, the build stops with the following error messge:
stdatomic.h(454): error: no instance of constructor "std::atomic_address::atomic_address" matches the argument list
argument types are: (const int *)
: atomic_address(_Ptr)
^
detected during:
instantiation of "std::atomic<T *>::atomic(T *) [with T=const int]" at line 304 of "../../include/QtCore/../../../../../../src/qt/qt5/qtbase/src/corelib/thread/qbasicatomic.h"

This is caused by a bug in the ICC-supplied stdatomic.h header. This has been reported to Intel and will be fixed in a future version of ICC.
The following patch fixes the issue:
