LLVM assert on proc groups

Context

        4e07d3f
        Odin:    dev-2024-10
        OS:      Windows 10 Professional (version: 22H2), build 19045.5011
        CPU:     11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz
        RAM:     16086 MiB
        Backend: LLVM 18.1.8

Current Behavior

LLVM assertion fires with Odin\src\check_expr.cpp(6457): Assertion Failure: `is_type_proc(proc_type)`

Failure Information (for bugs)

Steps to Reproduce

foo :: proc {
  foo_a,
  foo_b,
}

foo_a :: proc(a, b: int) -> int {
  return a;
}

foo_b :: proc(a, b: int) -> int {
  return a;
}

main :: proc() {
  x := foo(1);
}

The assertion happens if you call the proc. Otherwise it shows the error with
Error: Overloaded procedure 'foo_a' has the same type as another procedure in the procedure group 'foo' and so on.
The assertion doesn't happen if you have only one parameter in the procs.
