            Bug ID: 119752
           Summary: ranges::find does not handle volatile char ranges well
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hewillk at gmail dot com
  Target Milestone: ---

This is the sibling of PR119748:

https://godbolt.org/z/Mv184YGo8

#include <algorithm>

int main() {
  volatile char vc[4] = {'a', 'b', 'c', '\n'};
  auto it = std::ranges::find(vc, 'c');
}

Now I began to suspect if it was worth the trouble to review the entire
<algorithm>'s specialization for contiguous ranges one by one to ensure that
volatile arrays were supported...
