Re: Bug#43478: GCC internal compiler error while compiling current qt1g package

["Nikita V. Youshchenko" <yoush at cs dot msu dot su>]

The preprocessed file that causes internal compiler error it is the
attachment. It is src/widgets/menubar.cpp from qt-1.44 distribution.

It is interesting that if I move the headers to another path (but don't
change them!), the error disappears.
