I reproduced the failures with revision 133362 (and without
--disable-multilib). Reverting our patch (revision 133134) didn't help, I still
see the failures even without it.

I see same failures using compiler boostrapped with vectorization enabled using
BOOT_CFLAGS=-g -O2 -ftree-vectorize -maltivec -mabi=altivec
Tests fail because some loops were not vectorized:

After some regression hunting, I see that failures of vectorizer testcases
started after this patch:

Indeed my patch exposes additional vectorization abilities (which was
unexpected).
Kenny, can you run the failing testcase under valgrind?

I would suggest that you go roll back to that release mentioned in
message 1, where you have exactly the same code base for bootstrapped
and non bootstrapped compiler and run

On PowerPC-darwin, I started to get the following failures between

I wonder if the following patch could have caused the use of a variable after a
free:

I forgot to mention that valgrind does not find anything.
