⚠️ hebasto opened an issue: "build: Windows debug cross-build fails with `-O0`"
(https://github.com/bitcoin/bitcoin/issues/28109)
### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current behaviour

When cross-compiling for Windows with the `-O0` optimization level the build fails.

The error can be fixed by the `-Wa,-mbig-obj` assembler flag. However, @theuni [suggested](https://github.com/hebasto/bitcoin/pull/18#discussion_r1267219453):
> We should definitely look into breaking up that object.

### Expected behaviour

The build completes with no error.

### Steps to reproduce

@furszy makes an important point. Consider the case where I am paying someone on chain under the stipulation that *they* will eat the mining fee. (Thus, I specify *their* address in `subtractfeefrom` when I'm constructing my transaction.) Later, they tell me that they can't wait for confirmation any longer and need an urgent fee bump. If I naïvely specify their output as the `reduce_output`, I may end up paying them ***much more*** than I intended to if I only have large UTxOs in my wallet.

Concept ACK.

We don't consistently have clear variable naming (e.g. the ambiguous `hash`; or `txid` being used to refer to a wtxid), sometimes requiring quite a bit of developer time to figure out the expected ~type. I have experienced this quite a bit myself.

Introducing types makes this explicit at relatively low overhead, and I think the approach of subclassing `uint256` makes sense.

We'll have to be careful for this not to lead to unnecessary refactoring code churn, but that shouldn

I don't understand what the actual problem is, or what is broken? Can you elaborate?

I'm not an expert in assembly code, but "missing operand' sounds scary.

I don't know whether this warning is safe to ignore.

Probably needs some actual investigation then:
i.e what code + combination of compiler flags is causing the issue, produce a minimal test case.
Is this a "new" issue, or have the warnings existed in our codebase "forever".
Is it related to the fact that you're using ubuntu mantic (devel) and/or compiler/binutils versions etc.

I've definitely written/seen bugs that could be prevented if Txid and Wtxid were different types. When I review code it's something that I look for and it comes up surprisingly often. Interfaces taking `uint256` often implicitly expect them to be a txid, eg #23325.

Agree that checking at compile time would be nice and probably prevent bugs / make review easier. Concept ACK assuming we're ok with the amount of code change.

In terms of refactoring, this should be similar to the time type-safety PRs in that we can gradually convert our code.
