Spaces daemon dies via getptrblockmeta

[randomlogin]

I had some random regtest chain state and discovered that calling RPC method getptrblockmeta kills spaced.
Deleting regtest data folder and resyncing helped, problem no longer occurs.
It seems I somehow corrupted block data, but not sure how and when it happened.
I have not encountered the problem in any live chains.
For the sake of completeness I paste here the data that made the crash.

Steps to reproduce:

• download bitcoin block data, override your /regtest bitcoin chain data folder
• download spaced block data, override your /regtest spaced chain data folder
• call the following

curl -v -X POST http://127.0.0.1:7218/ -u "your_rpc_user:your_rpc_password" -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1337,"method":"getptrblockmeta","params":["2e77e7b819849626059c55969e3179f2914331b6dd17fc92166cb4580aa08980"]}'

hmm memory allocation of 2852009279487 bytes failed are you running out of memory?

Well, technically yes, I run out of memory, but it tries to allocate 2.83 terabytes of memory, which is a bit too much.
