; Currently the verifier when traversing the graph induced by the debug info

; metadata can reach the GV both from a DICompileUnit and a DIGlobalVariable

; expression, so we emit a diagnostic twice. This is, not ideal, but the

; alternative is that of keeping a map of visited GVs, which has non trivial

; memory usage consequences on large testcases, or when LTO is the mode of
