[lfs-dev] Broken sound (glibc).

 My shiny new LFS system is heading for /dev/null.  That's ok, it
was only a test of current packages, but I must admit I'd hoped to
keep it for a week or two.

 The reason is that although I've built everything except for some
gnome packages, I didn't test sound until last night.  Totally
broken.  gvolwheel reported it couldn't connect open the mixer,
although alsamixer runs ok.  aplay segfaults, but the segfault is in
ld-2.15.so.

 Google found that *some* people have been hitting this since
glibc-2.14.  It also pointed me to a patch at cross-lfs,
http://patches.cross-lfs.org/dev/eglibc-2.15-fixes-1.patch
which is from the libc-alpha list last year.  It applies (eglibc
isn't _that+ different :), but I'm reluctant to try upgrading the
running glibc - doing in-place toolchain updates is the beginning
of a slippery slope!

 I'll try a fresh test build, and this time test 'aplay' in chroot.
So, for the moment this is just a heads-up that I'm looking at this.

 Still puzzled about what suddenly broke this for me, LFS-7.1 on
this machine was fine but the problem first surfaced (for some
people) last summer.
