test: two builds of one module are refused before anything compiles The fixture is P -> M and P -> A -> M, where M's own flag --wide changes a struct it exports. Loaded with --wide --split, P gives M its args without --wide while A passes them on whole: Build(P) has to fail, name the module and both paths, and leave no bin/ anywhere. Loaded with --wide alone, both paths give M the same list, there is one M, and the build has to go through. Before the fix the first case built cleanly.
