Bug ID: 100990
Summary: Iterator checks for Debug Mode cannot be used with a
non-common range
Product: gcc
Version: 11.1.1
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
The Debug Mode iterator checks assume two iterators of the same type, so do not
work with an iterator and a sentinel.
It should be possible to use std::common_iterator like so:
__glibcxx_require_valid_range(common_iterator<_It, _Sent>(__it),
common_iterator<_It, _Sent>(__sent));
But wrapping a _Safe_iterator in common_iterator will prevent the checks from
making use of the additional information present in a _Safe_iterator (and maybe
prevent other checks from matching the iterator type?)
It would be nice to be able to use those debug mode assertions in ranges algos
and ranges::advance etc.
