V allocates too much memory

[MCausc78]

Describe the bug

<title>

Reproduction Steps

pub interface Component {
	is_component()
}

pub struct ActionRow {
pub:
	components []Component
}

fn (_ ActionRow) is_component() {}

pub fn (ar ActionRow) walk[T](f fn (T) bool) ?T {
    for c in ar.components {
        if c is T {
            if f(c) {
                return c
            }
        } else if c is ActionRow {
            if d := c.walk(f) {
                return d
            }
        }
    }
    return none
}

pub struct TextInput {
pub:
	custom_id string @[required]
	value ?string
}

fn (_ TextInput) is_component() {}

fn main() {
	ar := ActionRow{
		components: [
			TextInput{
				custom_id: 'foo'
				value: 'bar'
			}
		]
	}
	if d := ar.walk(fn (ti TextInput) bool {
		return ti.custom_id == 'foo'
	}) {
		println('value: ${d.value}')
	} else {
		eprintln('not found')
	}
}

Expected Behavior

Successful compile, without eating 1 gb

Current Behavior

I see in Process Manager that v.exe eats >32 GB of RAM (i have 64 GB of RAM)

In V playground:

Running code...
Can't run code. The server returned an error:
V panic: malloc_noscan(627) failed
v hash: cd337e2
C.backtrace returned less than 2 frames
Exited with error status 1
Please try again.

Possible Solution

Limit count of allocations

Additional Information/Context

When compiling my discord.v project, V eated 40 GB of RAM
