Backport from mainline 2019-07-31 Jonathan Wakely <jwak...@redhat.com> PR libstdc++/91308 * include/bits/unique_ptr.h (unique_ptr::__safe_conversion_up): Remove constraints on deleter that should only apply to the constructor. (unique_ptr<T[], D>::__safe_conversion_up): Likewise. (unique_ptr<T[], D>::unique_ptr(unique_ptr<U, D>&&)): Restore constraints on deleter here. * testsuite/20_util/unique_ptr/assign/91308.cc: New test.
