g++ 4.1.1 crashes when compiling the attached file with -finline-functions, which is enabled at -O3. The attached file belongs to media-video/kaffeine-0.8.1 . Removing finline-functions compiles it all right. This is the output I get: piojo@StarWars ~ $ LANG='' LC_ALL='' g++ -O1 -finline-functions -c kaffeine-crash.cpp kxinewidget.cpp: In member function 'QTime KXineWidget::getLengthInfo()': kxinewidget.cpp:3748: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions.
Created attachment 88851 [details] The preprocessed source that triggers the ICE.

Removing -O3 on that particular file omits the error. -O2 works fine
It's -finline-functions what fails. -O2 doesn't enable that optimization.
this will be fixed in gcc-4.1.1-r4 or gcc-4.1.2, whichever comes first
