3. Compile normaly
solc --bin-runtime C.sol
The output here does not match what I'm seeing on my machine. It's not the same as case 2 (that would definitely be a weird bug). It's still different than case 1, but has the same size. This indicates that just metadata hash differs. Indeed, without metadata hash both generate the same runtime bytecode. So this is essentially the same problem as already covered by #14986.
And yeah, the hash can affect the state of memory. Your contract C
is deploying a copy of D
, which means it has to copy it to memory. Since that copy of D
has metadata hash embedded in it, you'll definitely see some differences if you dump memory.
