Hi and thanks for the report. So this is quite an odd failure. Are you able to reproduce it easily? Which platform are you testing on?

Also if this is reproducible, can you please turn on core dumps and do a backtrace of the crashing location. I am hoping to see at least which test caused this failure.

BTW after some extensive golang-stress running (it continuously runs given binary on all cores; with intention to catch rare unit test failures) I am seeing this one rare failure (on master):

But this looks distinct from your failure. (Still I'll have a look at fixing it as well)
