--- Comment #3 from Ben Woodard <woodard at redhat dot com> ---
Another one that may be the same but may also be different is:
/usr/lib64/libQtGui.so.4.8.7 from qt-x11-4.8.7-59.fc34.x86_64

in this case it isn't the virtual table but it does seem to have the same
inexplicable type swapping:
 'const QSpinBox' changed to 'const QDoubleSpinBox'

So it is hard to say if it is the same or different. Is the key feature the
swapping of the types or is it the vtable changing? After seeing a few of these
I think that the cause is the type swap and the vtable change is caused by that
rather than the other way around.

  [C] 'method virtual void QSpinBox::fixup(QString&) const' at
qspinbox.cpp:928:1 has some indirect sub-type changes:
    Please note that the symbol of this function is
_ZNK14QDoubleSpinBox5fixupER7QString
     and it aliases symbol: _ZNK8QSpinBox5fixupER7QString
    'method virtual void QSpinBox::fixup(QString&) const
{_ZNK14QDoubleSpinBox5fixupER7QString, _ZNK8QSpinBox5fixupER7QString}' now
becomes 'method virtual void QDoubleSpinBox::fixup(QString&) const
{_ZNK14QDoubleSpinBox5fixupER7QString, _ZNK8QSpinBox5fixupER7QString}'
    implicit parameter 0 of type 'const QSpinBox*' changed:
      in pointed to type 'const QSpinBox':
        'const QSpinBox' changed to 'const QDoubleSpinBox'
