Crash two times in an hour.

Looks duplicate to #5633

Looks duplicate to #5633
cc @halfalicious

The new version(Aleth 1.7.0) crashed five times in 12 hours,The old version was about once every few months.

[halfalicious]

Interesting, I suspect that the "wait 2 seconds on disconnect" PR (#5707) is resulting in this crash being a lot more common, but just on Linux since I've been syncing for 12+ hours at a time several times over the past few weeks (on Windows) and haven't hit the segfault yet. @wifi-ctrl If you hit it again can you capture a full user-mode dump and share it with us? In the mean-time I'll try to repro on Linux.

@wifi-ctrl out of curiosity, what is online_wallet?

It is our online ETH wallet , we use Aleth 1.7.0 code and add some our own function.
We add this on old version too.

@wifi-ctrl If you build from source yourself, could you try please this branch?https://github.com/ethereum/aleth/tree/fix-sync-segfault
