Hi Igor,
Yes, I destruct rocksdb as part of static destruction. Should I not supposed to do so?

Thanks,
Wei

@hwpw can you open a separate issue for your problem? This is likely a result of either:

1. you keep using DB* even after the destructor kicks in, or
2. you destruct RocksDB as part of static destruction. You need to delete DB* before int main() finishes.

Yes, please delete RocksDB before the static destruction kicks in. RocksDB depends on statically allocated objects.

[igorcanadi]

@hwpw is this issue resolved now?

[hwpw]

yes it is resolved by explicitly destructing it before static destruction kicks in. Thanks!

[anip30]

Does explicit destruction mean I need to destruct it in destructor using delete operator?

[hwpw]

Yes, issue is fixed. Thanks!
