gcc-4.3.1 и странности

Здравствуйте.

Недавно я перешл на gcc-4.3.1 - все сделал правильно. Так вот выловились странности - теперь при компиле иногда система колом встает, просто ниначто не реагирует - ни клавиатура, ничего. Хотя компил идет - это видно. Даже мышкой можно возить, только на нажатия ничего неоткликается, даж музыка без прерываний играется. Но после компила - все встает в норму. Все собирается в оперативке (2гб для етого делала сделал), стоит сказать - что до гцц-4.3.1 все было хорошо. как поступать? спасибо.

P.S.
emerge --info
