@jkotas any hints how to troubleshoot this?

[MichalStrehovsky]

You need to scroll up for the error message but it's "error: Error in reading profile /repo/.packages/optimization.linux-x64.pgo.coreclr/1.0.0-prerelease.24369.3/data/coreclr.profdata: unsupported instrumentation profile format version".

Likely a mismatched version of clang in whatever docker container is used to build this in that pipeline.

[jkotas]

You either need to build with /p:NoPgoOptimize=true or use clang that is close enough to clang-18 in official build images.
