Null pointer dereference error in boost::bimap::insert() with strict gcc compiler warnings

When compiling code that calls e.g. boost::bimap::insert(1, 1) with GCC >=12.1.0 and strict warning flags (-Werror, -Wnull-dereference) and at least -O1, the compiler reports a potential null pointer dereference in std::less::operator(), a false positive.

"error: potential null pointer dereference [-Werror=null-dereference]
{ return __x < __y; }
~~~~^~~~~"

boost::bimap map;
**map.insert({1, 1});**

return 0;
