Subject: [v3 PATCH] PR libstdc++/78389
Authentication-results: sourceware.org; auth=none

Tested on Linux-x64.

This patch doesn't try to fix the reported sort() issue, because
a) it would require undoing a throwing move operation, which
is impossible.
b) in order to avoid the throwing move, we would need to add a
level of indirection and the scratch space for the indirect data
would need to be allocated.
