This was a recent regression caught by source-build. Here is the failing build (internal Microsoft link)
Inspecting the code, it seems strange that Last is used here but the two places following that reference correspondingSequencePoint check for null. Should Last be changed to LastOrDefault?
Building the runtime repo with a linker from https://github.com/dotnet/linker/commit/81ffbb5af38a45ff60648999df8f35a79061ae43 fails with the following:

?This is blocking source-build for RC1.
