The problem is that the semantic of the alias is run at the wrong time, i.e the error are not gagged but in the present context they should. The gagging is activated when the IsExp is visited. But the alias sema is run when the overload is inserted.

Created attachment 1779

workaround

As officially I dont participate to dlang anymore but also as a commit of mine causes the regression I send a patch.

The fix is not really good but comes with explanations about what was done in first place, i.e for issue 15795. Ideally issue 15795 should be fixed in another way but I remember that I could not find a better way when I made the PR.

--- Comment #6 from Basile-z <b2.temp@gmx.com> ---
Ok I've find what really happens. When you merge the two tests in a single
module, so the one reported here and the one here
https://github.com/dlang/dmd/pull/10078/files#diff-b33aefca6dc2d2014d789a2d8727fb1eR1,
then this compiles because symbols are solved differently.
