Anvil seems not to be compatible with returning data from the constructor of a read-only deployment eth_call

[Gilgames000]

I've been using a library that supports deployless multicall on networks where the contract is not deployed or if you try to fetch historical state at a block number where the multicall contract was not available. It works with all the nodes I tried (Infura, Alchemy, Tenderly, Hardhat, etc.) except Anvil, where it seems to return 0x as the data.

From the deployless multicall Solidity implementation repo :

Normally, a consturcor in Solidity contract returns the bytecode of the newly created contract. Here, we use inline assembly to overwrite return data with the call result.

The code makes some assuptions about how the variables stored in memory, so it's better to stick to Solidity version specified in the contract.

Is this intended behavior in Anvil?
