I am using Boost.Test (in header-only mode, using "included"), for a Boost-aspiring project https://github.com/correaa/boost-multi

I am getting this warning with MSVC 143:

D:\a\boost-multi\boost-multi\vcpkg\installed\x64-windows\include\boost\test\impl\progress_monitor.ipp(62): warning C5045: Compiler will insert Spectre mitigation for memory load if /Qspectre switch specified [D:\a\boost-multi\boost-

https://github.com/correaa/boost-multi/actions/runs/10066511703/job/27828050365#step:9:62
