Possible allocator memory corruption?

[SUPERCILEX]

Describe the Bug

Unfortunately, I'm not sure. Using wee_alloc causes bugs in Bevy, suggesting a bug somewhere in the allocator.

Steps to Reproduce

See https://github.com/bevyengine/bevy/issues/3763

Expected Behavior

No memory corruption bugs.

Actual Behavior

Memory corruption.

it also seems to never actually free any memory and will eventually oom even with the most basic bevy app.

#[global_allocator]
static ALLOC: wee_alloc::WeeAlloc = wee_alloc::WeeAlloc::INIT;

#[wasm_bindgen]
pub fn run() {
    App::new()
        .add_plugins(DefaultPlugins)
        .run();
}

using the default allocator works as expected
