You might want to try delta:
 http://www.cs.berkeley.edu/~dsw/
I use the following script with delta to reduce stuff like this:
#!/usr/bin/python
# Using delta debugging on GCC input
#import psyco
#from psyco.classes import *
import commands
import string
import sys

# Invoke GCC
(status, output) = commands.getstatusoutput("/Users/pinskia/local.c/libexec/gcc/powerpc-apple-
darwin7.9.0/4.1.0/cc1plus -quiet  --param ggc-min-expand=0 --param ggc-min-heapsize=0 
-Wfatal-errors %s 2>&1" % sys.argv[1])

# Determine outcome
if status == 0:
  sys.exit(1)
elif string.find(output, "finish_compound_stmt") >= 0:
  sys.exit(0)
else:
  sys.exit(1)
