I'm seeing the following runtime debug warning (on master), but cannot trace it any where in the code:

[14:19:08.043] warning: Using the same data path for profile, may corrupt the data.

Windows 11, MSVC 2022_64

Internet search suggests, but why report it at runtime?

Profile-guided optimization (PGO) in MSVC uses profiling data collected during a trial run of the application to guide optimizations in subsequent builds. If the same data path is reused across multiple profiling sessions without proper cleanup, it can lead to corrupted or conflicting profiling data.
