[gentoo-user] Strange ALSA issue

[Marc Morrisette]

I just got done following the GCC migration guide on 3 computers.  It went smoothly on 2 of them, everything works fine, but on the third, after I recompiled the kernel, alsa-driver won't compile.  I'm using vanilla-sources 2.6.14.2, the kernel options are all identical to what they were before I did the GCC migration.  It's getting stuck very early in the ALSA compile:

I have no idea how to solve this...it's only happening on one computer.  On the others, ALSA compiled fine after recompiling the kernel with the new compiler.  The only change that I made after switching compiler was changing my CFLAGS.  3.3.6 didn't have a --march entry for my processor, so I had to use i686.  After the GCC update, I changed the CFLAGS to --march=c3-2, then I did emerge -e system and emerge -e world afterwards.  Everything but ALSA is working fine.  I'm lost here, I can't imagine what the problem could be.  ALSA would've been recompiled as part of world after the GCC upgrade/CFLAGS change, it must've worked then as I didn't get any errors from the emerge.
