Маленький разбор полетов.

Совпадают символы

T       __builtin_delete
T       __builtin_new
T       __builtin_vec_delete
T       __builtin_vec_new
T       __pure_virtual

такие символы в принципе можно добавить в черный список, но мне не
совсем понятно, почему они появляются.  Они должны либо вообще
инлайнироваться, либо сидеть в shared libgcc.

Совпадают симолы

T   NP_GetMIMEDescription
T   NP_GetValue
T   NP_Initialize
T   NP_Shutdown

Т.е. это "точки входа" в плагин, насколько я понимаю.
К сожалению, робот этого не понимает.

Дублирование библиотек хорошо обнаруживается, на уровне примерно 5-10.

firefox статически слинкован со своей же собственной libxul?

Эти пакеты таскают с собой bonobo?  Или это интерфейсы компонентов?


Короче: не понятно, почему дублируются __builtin_*.
