@TautvydasZilys that is the versions of VC++ runtime the problem is experienced on ?

Here is the short analysis of the problem: - `global_control` related C++ [static objects](https://github.com/oneapi-src/oneTBB/blob/3e352b48127b3c79d61df5618607d2daab3f2caa/src/tbb/global_control.cpp#L149-L153) are being initialized. - These objects have a `std::set` as a [member](https://github.com/oneapi-src/oneTBB/blob/3e352b48127b3c79d61df5618607d2daab3f2caa/src/tbb/global_control.cpp#L45). - `std::set` default constructor...

It seems that `zero_allocator` was removed by mistake. However : - it seems that the only use case for it is the "waiting for element construction" in the concurrent_vector (as...

@mweisgut can you share more details on your use case of `zero_allocator` ?

@rfschtkt is this applicable to oneTBB ?

@dr-pain, as I see from https://github.com/oneapi-src/oneTBB/blob/master/integration/windows/env/vars.bat and https://github.com/oneapi-src/oneTBB/blob/master/integration/windows/env/vars.bat.in quotes are in place. Could please confirm that problem is not reproducible with oneTBB?

clang-tidy might [help ](https://clang.llvm.org/extra/clang-tidy/checks/performance-noexcept-move-constructor.html) to find move constructors and assign operators
