The current version of the Webassembly linker `wasm-ld` allows the argument `--page-size=N` with N being either `1` or `65536` since the merging of #128942. For some reason, when also passing the `--import-memory` flag, the `page-size` is completely disregarded without telling the caller. This results in `.wasm` files that try to import a memory with the default page-size even if `--page-size=1` was given.
# How to reproduce
I don't know anything about linkers and discovered that while compiling rust code to wasm bytecode so it's what I'll describe.
Setup :
```bash
rustc -Vv

```
```
cargo new --lib wasm-ld-bug-test
cd wasm-ld-bug-test
