Description
The 11438 revision added restrictions for Clang 3.4 compiler in uppsrc/Core/CoWork.h file.
I propose to remove such restriction and take informative approach instead, because possible to use other -std value (e.g. -std=c++11) for more modern compiler with the same "not compiled" effect.

#1 Updated by Sender Ghost over 6 years ago
This was tested on FreeBSD 10.3 amd64 and Clang 3.4.1 in base (with using -std=c++1y instead of -std=c++14) for example in tutorial/CoreTutorial/Async.cpp:
https://github.com/ultimatepp/mirror/blob/3231859d0295b96ee2ce53ee00578d6227ba7279/tutorial/CoreTutorial/Async.cpp
with following results:
a.Get() = 9.33262154439441e157 Exception has been caught Work was canceled
