Description
Required prerequisites
- Make sure you've read the documentation. Your issue may be addressed there.
- Search the issue tracker and Discussions to verify that this hasn't already been reported. +1 or comment there if it has.
- Consider asking first in the Gitter chat room or in a Discussion.
What version (or hash if on master) of pybind11 are you using?
2.11.1
Problem description
When working ,I encountered a problem that need to bind std::vector<std::pair<int64_t, pybind11::bytes>> such type in pybind11.
but this build failed in VS.
report error C4996: 'pybind11::handle::operator ==': Use obj1.is(obj2) instead
message : see reference to function template instantiation 'bool std::operator ==<int64_t,pybind11::bytes>(const std::pair<int64_t,pybind11::bytes> &,const std::pair<int64_t,pybind11::bytes> &)' being compiled
Did I do something wrong? I use std c++20 and pybind11 2.11.1.
Looking forward to reply. Thanks
Reproducible example code
std::vector<std::pair<int64_t, pybind11::bytes>> _LoadFlow(const std::string& filename)
namespace py = pybind11;
PYBIND11_MAKE_OPAQUE(std::vector<std::pair<int64_t, py::bytes>>);
PYBIND11_MODULE(flow_loader, m) {
py::class_<FlowLoader>(m, "FlowLoader")
.def(py::init<>())
.def("load_flowfile", &FlowLoader::_LoadFlow)
py::bind_vector<std::vector<std::pair<int64_t, py::bytes>>>(m, "VectorPair");
}
Is this a regression? Put the last known working version here if it is.
Not a regression

Research direction
Start by reproducing the Visual Studio C4996 failure with the shown std::vector<std::pair<int64_t, py::bytes>> type, PYBIND11_MAKE_OPAQUE, and py::bind_vector entry points. No source files or tests are named; inspect the binding implementation and existing coverage to establish whether this combination should compile, with completion requiring a verified resolution or clearly documented limitation.
