Description of problem:

GCC internal error while compiling linux-git head with make defconfig ARCH=um;
make linux ARCH=um

Version-Release number of selected component (if applicable):

gcc (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8)

How reproducible:

always.

Steps to Reproduce:
1. git-clone
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git your_dir
(will probably fail the same way with a 2.6.25-stable tree)
2. cd your_dir
3. make defconfig ARCH=um
4. make linux ARCH=um and wait a bit ;)
  
Actual results:

  CC      kernel/sched.o
In file included from kernel/sched.c:1486:
kernel/sched_idletask.c: In function ‘check_preempt_curr_idle’:
kernel/sched_idletask.c:20: erreur interne du compilateur: dans
cgraph_estimate_size_after_inlining, à ipa-inline.c:188


Expected results:

compiles flawlessly.
