C Error. Compiler bug when directly passing index from json (and alike?) data

[ttytm]

Describe the bug

I didn't know a good and short title that would fit. I hope an example can do most of the talking for me.

import x.json2
import net.http

struct SomeStruct {
	title string
}

fn main() {
	resp := http.get('https://jsonplaceholder.typicode.com/posts/1')!
	raw_data := json2.raw_decode(resp.body)!

	data := raw_data as map[string]json2.Any

	mut ss := map[int]SomeStruct{}
	s := SomeStruct{
		title: data['title']!.str()
	}

	// Compiler bug putting `data['id']!.int()` directly into ss[].
	ss[data['id']!.int()] = s

	// No issues with id in variable
	// id := data['id']!.int()
	// ss[id] = s

	println(ss)
}

Got a few of these C errors this week, I report more when I have time.

Expected Behavior

Current Behavior
