Heyho! I strongly suspect that mixing -flto and -g might not be a well supported option right now ...
Still I also suspect an ICE is not supposed to happen. (I was trying to recompile Debian's KDE packages with -flto; the packaging by default uses -g - O2) gcc Debian package 4.5.0-2 on amd64 (x86-64) +++ $ gcc-4.5 --version gcc-4.5 (Debian 4.5.0-2) 4.5.1 20100419 (prerelease) Copyright (C) 2010 Free Software Foundation, Inc.
