Unresolved external symbol in the C++ standard library for builds on image 20220814.1 #6091
Description
Description
Our build pipelines started failing today with the rollout of image 20220814.1 for windows-latest VM images.
We use vcpkg in our repo, and install the benchmark library with it, and build one of our target exes against that library. The library calls something in the standard library that uses _Find_unchecked which calls __std_find_trivial. The error is a linker error so somehow it is finding a forward declaration in the header file but not actually building the function, so by the time we are linking it, we hit unresolved external symbol errors.
We are completely blocked from building due to this. It doesn't repro on our local dev machines. Some of us have VS2022 17.2, some 17.3. None of us are hitting this build error locally - it only happens on the VM images.

Image version and build link
20220814.1
All of our builds are failing when built on machines with the new image because we link against the vcpkg benchmark library, and somehow it is compiling against in the standard library, fidns __std_find_trivial forward declared, but doesn't actually compile the function, resulting in a linker error due to an unresolved external symbol.
Is it regression?
20220808.1
Expected behavior
'benchmark' vcpkg package can be used as a dependency and linked successfully
Actual behavior
Build fails because google benchmark library included with vcpkg somehow has an unresolved external symbol from the standard library. This doesn't repro in the previous image or on our local dev machines.

Repro steps
The only repro we know of is to build our project.
