Compiler assert failure when aliasing a package and using it in the file scope of another file

[jv-guimaraes]

Context

    Odin:    dev-2024-08-nightly:6fe938b
    OS:      Windows 10 Unknown Edition (000000bf) (version: 21H2), build 19044.4651
    CPU:     AMD Ryzen 5 4600G with Radeon Graphics
    RAM:     15761 MiB
    Backend: LLVM 18.1.8

Expected Behavior

The compiler should display an appropriate error message instead of crashing.

Current Behavior

The compiler crashes with a null pointer assertion when compiling a program that uses a package alias defined in one file and referenced in another file's global scope.

package test

import "vendor:raylib"

rl :: raylib

main :: proc() {
}

package test

outside := rl.WHITE // this crashes

func :: proc() {
    inside := rl.WHITE // but this is fine
}

It with the following error:
D:\a\Odin\Odin\src\checker.cpp(4556): Assertion Failure: d != nullptr
The crash occurs most of the time, but occasionally the compilation succeeds. When compiled with -thread-count:1, it crashes 100% of the time.
