I believe it is caused by Xcode 16.3 that introduces a backwards-incompatible change. See the release notes [deprecations](https://developer.apple.com/documentation/xcode-release-notes/xcode-16_3-release-notes#Deprecations) that states:

> The base template for `std::char_traits` has been removed. If you are using `std::char_traits` with types other than `char`, `wchar_t`, `char8_t`, `char16_t`, `char32_t` or a custom character type for which you specialized `std::char_traits`, your code will stop working. The Standard does not mandate that a base template is provided, and such a base template is bound to be incorrect for some types, which could previously cause unexpected behavior while going undetected.

It looks like the V8 dependency is the main contributor here, so I imagine that this needs to be fixed upstream. I can't be 100% that there are not other parts in the code base that have the same issue though.

For the record: switching back to Xcode 16.2 works around the problem.
