Created an attachment (id=5851)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=5851&action=view)
preprocessed failure case

I extracted the failing file from the full build and this is the preprocessed
output along with a smaller command line.  It compiles at -O1 but gives the
ICE at -O2.  

./xgcc -B./ -B/opt/rtems-4.7/arm-rtems4.7/bin/	 -O2	-mthumb  -c

regression from 3.3.2.  I verified the test case compiles with the same 
binutils and older arm-rtems-gcc.
