Compiles OK for original and reduced testcase (-O2 -ftree-vectorize) with:
Target: x86_64-unknown-linux-gnu
gcc version 4.3.0 20070622 (experimental)
Also works OK when (-m32 -msse3) is added to activate 32bit compilation.
BTW: I plan to add the testcase from Comment #11 to vectorizer testsuite.
Also note that this PR is not marked as a regression on 4.0/4.1/4.2 so it
should be either marked as a regression or should be closed as the testcase
compiles OK.
