[libcxx-commits] [PATCH] D131868: [libc++][NFC] Refactor enable_ifs in vector

[Louis Dionne via Phabricator via libcxx-commits]

ldionne added a comment.

I am 90% certain that this caused the following change of behavior: https://godbolt.org/z/WKEadqf8e. Long story short, constructing a vector with iterators with a mismatched constness used to work, and now it doesn't anymore. GCC doesn't support it either.

@philnik Since this is almost certainly unintended, can you please figure out what the valid standard behavior is here and add a test if the standard mandates that?
