Possibly due to: https://developercommunity.visualstudio.com/t/Illegal-Instruction-SSE-42-POPCNT-exc/10520578 https://developercommunity.visualstudio.com/t/Illegal-Instru... tl;dr is that an SSE4.2 instruction was introduced into an optional but commonly used runtime library that ships with the Visual C++ compiler. There's no runtime checking for whether the CPU supports this instruction, so it crashes on older CPUs.
