This will get fixed with the recent 2.0 release which needs python-sphinx-tabs.

This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.

I'm confident this is a package bug.  GCC is emitting a diagnostic for this code in ImageDesc.cpp

       if(const PackedImageDesc * packedImg = dynamic_cast<const PackedImageDesc*>(&img))
        {
            os << "<PackedImageDesc ";
            os << "data=" << packedImg->getData() << ", ";
            os << "width=" << packedImg->getWidth() << ", ";
            os << "height=" << packedImg->getHeight() << ", ";
            os << "numChannels=" << packedImg->getNumChannels() << ", ";
            os << "chanStrideBytes=" << packedImg->getChanStrideBytes() << ", ";
            os << "xStrideBytes=" << packedImg->getXStrideBytes() << ", ";
            os << "yStrideBytes=" << packedImg->getYStrideBytes() << "";
            os << ">";
        }
        else if(const PlanarImageDesc * planarImg = dynamic_cast<const PlanarImageDesc*>(&img))
        {
            os << "<PlanarImageDesc ";
            os << "rData=" << planarImg->getRData() << ", ";
            os << "gData=" << planarImg->getGData() << ", ";
            os << "bData=" << planarImg->getBData() << ", ";
            os << "aData=" << planarImg->getAData() << ", ";
            os << "width=" << packedImg->getWidth() << ", ";
            os << "height=" << packedImg->getHeight() << ", ";
            os << "yStrideBytes=" << planarImg->getYStrideBytes() << "";
            os << ">";
        }
 
Note that packedImg will be NULL in the else-if block.  Hence this diagnostic:

This is not a GCC error, but clearly an error in the package that the package maintainer will need to fix.

Hopefully this is fixed in 2.0. I recently got python-sphinx-tabs into Fedora.

Jeff, any hints on how to fix? This one is beyond me. Upstream has acknowledged the issue but doesn't have time to fix with 2.0 being released but there are still a couple of packages, Blender most notably when isn't ready for 2.0.
