Segfault with aliased package in a sibling file

[Feoramund]

Context

Odin:    dev-2024-04:a61ae7c86
OS:      Arch Linux, Linux 6.8.5-arch1-1
CPU:     12th Gen Intel(R) Core(TM) i7-12700K
RAM:     31916 MiB
Backend: LLVM 14.0.6

The following scenario causes a segmentation fault:

main.odin

package main

import "core:fmt"

import "b"

main :: proc() {
    fmt.println(b.test())
}

a/a.odin

package a

test :: proc() -> int {
    return 4
}

b/b.odin

package b

import "../a"

a :: a

b/b_2.odin

package b

test :: proc() -> int {
    return a.test()
}

lldb output
