Just saw this today during a crash when creating Materialized Views. It is still unclear why this happened. But the message says: Mar 28 15:55:58 ip-172-31-24-9 scylla[14055]: scylla: sstables/sstables.cc:2973: sstables::sstable::remove_sstable_with_temp_toc(seastar::sstring, seastar::sstring, seastar::sstring, int64_t, sstables::sstable::version_types, sstables::sstable::format_types)::<lambda()>: Assertion `tmptoc == true' failed.

That's because those asserts are the very first thing we do. We can discuss whether or not assert is the right behaviour (usually we can't guarantee the state is sane if that is missing, so I don't see a problem) But it would be nice to see which SSTable we are processing before we assert.
