warning C4296: '>': expression is always false

[kkumar45]

Hi,

Our application treats warning as error.

We are seeing below warning on windows with Visual Studio 2017 after upgrading to TBB 2020.  It's coming from tbb "concurrent_unordered_set.h" header.

Below program helps to generate the warning. 

Error details:

tbb\concurrent_unordered_set.h(229): error C2220: warning treated as error - no 'object' file generated
tbb\concurrent_unordered_set.h(235): note: see reference to alias template instantiation 'cu_set_t<tbb::interface5::concurrent_unordered_set,std::iterator_traits<_Iter>::value_type,>' being compiled
tbb\concurrent_unordered_set.h(229): warning C4296: '>': expression is always false

#include <tbb/concurrent_unordered_set.h>

int main() 
{
    return 0;
}

I apologize for the lack of response to your thread. I have tested this with Visual Studio 2019 using the latest version of Intel® oneAPI Threading Building Blocks and this behavior is not occurring. Please try again with the latest version.

I am closing this thread for Intel support. Any future replies will be considered community only.
