It looks like we instrument code for GC stress only on the JIT-compile code path. Thus R2R code can't run through GC stress.

We should consider supporting R2R code in GC stress as well. It may just mean to call SetupGcCoverage at some appropriate point when R2R code is loaded.

Ah that reminds me of #10184 -- has it been 6 years since we had GC stress for prejitted code?
