            Bug ID: 81885
           Summary: operator-> not checked by -D_GLIBCXX_ASSERTIONS
           Product: gcc
           Version: 7.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: joerg.richter@pdv-fs.de
  Target Milestone: ---

unique_ptr::operator* is checked with __glibcxx_assert. But
unique_ptr::operator-> uses only _GLIBCXX_DEBUG_PEDASSERT. I think the later
can use __glibcxx_assert too.

Same for the other pointer templates.
