You're right that returning `Db` instead of `ref Db` "fixes" the problem, but is that really a solution? Returning a "ref" simply means that `load_rdb()` is really a Db constructor. That should work.
And no, an alias for `DbRef = ref Db` does _[not](https://forum.nim-lang.org/postActivity.xml#not) fix it. Same for `DB = ref object`. Still crashes.... ... Oh! Your clue helped me find the problem. let scanned = sscanf(line.cstring, v_frmt.cstring, addr result.version) Run "version" there is a string, not a cstring, so this is over-writing the ref-counting data. I really, really want the "newruntime". This kind of mistake is way too easy.
