It appears that updating to Visual Studio 2019 16.6.0 breaks Intel C++ 19.1 Update 1. I'm seeing incorrect std::find behavior but there may be other issues. I realize that 16.6 isn't listed in the (not always accurate or up to date) compatibility doc but I thought I'd note this issue here for the sake of other Intel C++ users. If anyone knows a work-around that would help since downgrading VS is non-trivial.
