Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
>How-To-Repeat:
Every compilation of this code should do it.
>Fix:
It can be workaround like this:

template QArray<something>;
extern QArray<something> x;

but the compiler should not crash I think ;)
