Really seems a c++, not libstdc++ bug and I'm tentatively changing
its category.

Below a reduced testcase, with two workarounds in comments.

Nathan, could you possibly have a quick look?

Thanks in advance!
Paolo.

#include <iterator> 
#include <cassert> 

int main() 
{ 
  typedef std::reverse_iterator<const char*> RI;

  // char s[] = "0";
  const char s[] = "0";

  // RI r1(s);
  RI r1 = RI(s);

  const char* n1 = r1.base();
  assert( n1 == s );
}
