It should be valid to use std::to_address on a past-the-end iterator, but the debug mode iterators do a check for dereferenceable in their operator->(). That check is generally useful, so rather than remove it this changes std::__to_address to identify a debug mode iterator and use base().operator->() to skip the check. PR libstdc++/93960 * include/bits/ptr_traits.h (__to_address): Add special case for debug iterators, to avoid dereferenceable check. * testsuite/20_util/to_address/1_neg.cc: Adjust dg-error line number. * testsuite/20_util/to_address/debug.cc: New test. |
