            Bug ID: 83755
           Summary: Pretty printers treat char* as NTBS
           Product: gcc
           Version: 7.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
  Target Milestone: ---

#include <memory>
int main()
{
  char a[] = {"abcd";
  std::unique_ptr<char> p(&a[0]);
  p.release();
}

This prints:

$1 = std::unique_ptr<char> containing 0x7fffffffd38b "abcd"

The stored pointer is not a NTBS, it's just a single char.
