SPEC2006 403.gcc is miscompiled so we ICE building scilab.i:
scilab.i:12953: Internal compiler error in remove_useless_values, at
cselib.c:394
flags used for building 403.gcc are -O3 -funroll-loops -fpeel-loops
-ftree-vectorize. (base with -O2 still works ok)
The change happened between r125530 (last working rev) and r125567 (first
failing rev).

------- Comment #1 from victork at il dot ibm dot com 2007-08-01 11:24 -------
I've tried to build and run SPEC2006 403.gcc using r126903 and it did *not*
fail.
I've used following optimization flags in configuration file:
#####################################################################
# Optimization
#####################################################################
## Base is low opt
default=base=default=default:
COPTIMIZE = -O3 -funroll-loops -fpeel-loops -ftree-vectorize
CXXOPTIMIZE = -O3 -funroll-loops -fpeel-loops -ftree-vectorize
FOPTIMIZE = -O3 -funroll-loops -fpeel-loops -ftree-vectorize
