@oli-obk ideally the error would point not only here, but also at line 14 where the constant syntactically appears. Any idea why it doesn't do that?

hmm... good point ^^ probably an oversight in the mono time error handler

RalfJung · 2023-10-07T23:57:08Z

In fact whether the span at no_codegen::<i32>(); is shown seems to depend on the optimization level?

@bors r+ rollup
