Maybe that is not all issues. It was shown before build stopped.

I just pushed a fix to "hotfixes" branch. Please try it and let me know whether it works for you.

[slyshykO]

Sorry, but still not work. Error in Allocators.h remains. Added few new errors: D:\projects\cpplibs\embxx\module\util\test\EventLoop.th:250:18: error: but 'EventLoopTestSuite::test5()::<lambda()>' does not throw; perhaps it should be declared 'noexcept' [-Werror=noexcept] &ready ^

If it required I can send full build log.

Tested under Ubuntu 16.04:

• success build with g++ (system default)
• fail with g++-7.2

[arobenko]

Sorry, I haven't really touched this project for 4-5 years and I don't know when I will come around to test latest compilers and fix all the problems. If you wish you can try to fix them yourself and submit a pull request.

[slyshykO]

Ok, I'll try.
