Double lock detected in Warnings::GetMessages() #30400
Description
Is there an existing issue for this?
- I have searched the existing issues
Current behaviour
Running bitcoin-qt -testnet results in it eventually deadlocking due to a double lock in the warnings code.
Expected behaviour
Should not double lock.
Steps to reproduce
- Build with
--enable-debug(or defineDEBUG_LOCKORDER - Run
bitcoin-qt -testnet, and either sync or reindex - It will assert and crash on its own (without
DEBUG_LOCKORDER, it will eventually hang)
