When I use gcc 3.4.2-r2, compiling the 2.4.27 gentoo kernel it breaks while compiling bzImage almost immediately, However, If I emerge gcc 3.3.4, it seems to compile fine... and the when I emerge gcc 3.4.2-r2, it fails to compile once again. I noticed in 3.4.2 gcc uses athlon automation... 48 NDFA states, 90 NDFA arcs > 48 DFA states, 90 DFA arcs > 20 minimal DFA states, 62 minimal DFA arcs > 29 all insns 16 insn equivalence classes etc, etc, while in gcc 3.3.4 it uses pentium? My CPU is an athlon-xp 2600+ Reproducible: Always Steps to Reproduce: 1. emerge gcc 2. genkernel -menuconfig all 3. Actual Results: Compilation Failed.

my suggestion is to either use a 2.6 kernel or wait for 2.4.28, which apparently has a number of gcc 3.4 fixes. the bug is in the kernel, not the compiler.
