The failure is not a consistent repro, but I see it fail about 50% of the time. It will fail without GCStress as well, if you are "lucky". The failure mode also changes, but always looks like one of the set of common GCStress asserts.

set COMPlus_TieredCompilation=0
set COMPlus_TailcallStress=1
set COMPlus_GCStress=C

I ran this test in a loop for many iterations but wasn't able to repro the failure with recent sources. I will re-enable the test.

Fix TailCallStress mode.
415e98e 
Improve validation of tail calls that are not tail-prefixed in the IL
but are marked as such because of TailCallStress. We now do the same
correctness validation in morph for such tail calls as we do for
implicit tail calls. That blocks tail calls when we have address-taken
locals, struct promoted params, and pinned vars.
