Undefined symbol when importing module in python

Hi guys

I''m trying to use boost python and then I'm exposing simple class i get
undefined symbol: _ZN5boost6python15instance_holder8allocateEP7_objectmm

I checked symbols in libboost_python39.so.1.78.0 and i noticed that exist following symbol
_ZN5boost6python15instance_holder8allocateEP7_objectmmm (one m more than expected)

So am I doing sth wrong or this is a bug?

My class
```
struct ConnectionFactory
{
ConnectionFactory(){}
~ConnectionFactory(){}
};
```

Exposing by:
`class_("ConnectionFactory");`

Linux Ubuntu 18.04

EDIT:
I made a workaround, just modifying expected symbol using this
`objcopy --redefine-sym _ZN5boost6python15instance_holder8allocateEP7_objectmm=_ZN5boost6python15instance_holder8allocateEP7_objectmmm myFile.o`

And this is working, but i'm not sure if this is correct approach

Start by comparing the expected and exported symbols in libboost_python39.so.1.78.0 against the shown ConnectionFactory exposure on Ubuntu 18.04. Review the objcopy workaround and determine whether the mismatch is reproducible and whether it indicates a Boost.Python or build configuration problem.
