Following (delta reduced) testcase ICEs with 'gcc -O2 -msse2
-ftree-parallelize-loops=4 -ftree-vectorize' on i686 and x86_64:

gcc -O2 -msse2 -ftree-parallelize-loops=4 -ftree-vectorize 048.c
048.c: In function 'Create_BCyl':
048.c:15: internal compiler error: in build2_stat, at tree.c:3110
Please submit a full bug report,
