Thanks for the report. We were missing a check of `CI.isUnwindAbort()` in CoroSplit.cpp's `shouldBeMustTail()` function -- fixed for next version of the series. (It's not a regression in tail-callability for coroutines, since that `call unwindabort` would've previously been an `invoke`, which also cannot be musttail'd.)
