            Bug ID: 118494
           Summary: std::counting_semaphore<PTRDIFF_MAX> should work
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
            Blocks: 88322
  Target Milestone: ---

Currently we use __platform_wait_t internally, which is int on Linux. That
means we only support up to std::counting_semaphore<INT_MAX>.
