MSVC 17.10.0 + modules cannot find definition #3972

Closed matt77hias closed 1 month ago

matt77hias commented 1 month ago

MSVC regressed since the new 17.10.0 compiler update. node<> cannot be found for detail::dynamic_arg_list::typed_node.

error C2504: 'fmt::v10::detail::dynamic_arg_list::node<void>': base class undefined

I have not checked the non-modules path, but I assume you have CI coverage for that.

This looks like an MSVC bug. Could you report to Microsoft?

vitaut commented 1 month ago

And once reported to Microsoft please add a link to that report here so that we knew when the issue is fixed.

Fyi I do not use dynamic_format_arg_store directly, but it seemed the easiest way to trigger the error.

Merged, thanks
