; This test case has two scops in a row. When code generating the first scop,
; the second scop is invalidated. This test case verifies that we do not crash
; due to incorrectly assuming the second scop is still valid.
; We explicitly check here that the second scop is not code generated. Later
; improvements may make this possible (e.g., Polly gaining support for
; parameteric conditional expressions or a changed code generation order).
; However, in case this happens, we want to ensure this test case is been
; reasoned about and updated accordingly.
