            Bug ID: 101659
           Summary: _GLIBCXX_DEBUG mode for std::optional ?
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: simon.marchi at polymtl dot ca
  Target Milestone: ---

There doesn't seem to be a version of std::optional with debug runtime checks
enabled with _GLIBCXX_DEBUG.  It seems to me like it would be useful, to catch
"dereferencing" the optional when it doesn't contain a value.
