Description of problem:

The latest gcc 4.7 experiences an ICE while building guile on arm systems.


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

gcc-4.7.0-0.9.fc17 (what breaks)
guile-1.8.8-4.fc17.2 (what breaks it)

How reproducible:

Every time.

Steps to Reproduce:
Build guile on arm.koji.
  
Actual results:
