Hey everyone!

Thanks! That solved an issue for me:

Lately, the GNU Radio MinGW CI has been failing, but I have had a terrible time figuring out why. (I'm really not a fan of the Github runners, which make introspection of something failing basically impossible before it fails, local reproduction hard, and pairing that with rolling-release nature of Msys2 made it impossible to just look into what changed.

So, without Ryan pointing at this, and Gisle asking about it, I wouldn't have been able to figure this one out!

Should have asked, myself, it seems! Glad someone did :) Even more glad some 
answered!

Best regards,
Marcus

So I ended up with:
   pip3 uninstall pybind11
   pip3 install pybind11==3.0.1

Has anybody else seen such issues with pybind11 3.0.2?



Hi,

I have seen the same recently in building the `gnuradio` package for conda-forge. It seems to be an upstream bug:
https://github.com/pybind/pybind11/issues/5989

Good to know I'm not the only one. Thanks for the link.


For now I have also fallen back to building with pybind11 3.0.1 and hope the pybind11 developers will address it in the next release.
