It could, but not for *those* symbols. Exceptions require the typeinfo for the
type being thrown (which is why cross-library exceptions sometimes fails with
-fvisibility=hidden), but none of these types should be thrown:
QFocusHelper
QAbstractUndoItem
QStaticTextUserData
QItemEditorCreatorBase
QNetworkConfiguration
(some of those classes look like they came straight from classnamer.com)
To the OP: find out which .o requires those TI symbols.
Also, since I guess you're not using GCC, I can't rule out a compiler bug
either.
