[PATCH] D60023: [libcxx] [test] Fix inability to rebind poca_alloc in string.cons/copy_alloc.pass.cpp.

[Billy Robert O'Neal III via Phabricator via cfe-commits]

BillyONeal added a comment.

Tim Song suggests that http://eel.is/c++draft/string.require#2 indicates that basic_string actually does need to provide the strong guarantee here. While I think that wording is a mess I think I'll fix our basic_string to do that instead of that part of this change.
