I think that following difference is the key:
In case vectorizer is able to vecotrize, we enter vectorizer pass with:
:
# ivtmp.17_1 = PHI
# i_18 = PHI
# s_17 = PHI
D.2002_7 = a[i_18];
D.2003_8 = i_18 + D.2

I have noticed, that following text is missing from your vect dump:
Dependence tester statistics:
Number of dependence tests: 0
Number of dependence tests classified dependent: 0
Number of dependence tests classified ind

Adding __attribute__((aligned(16))) doesn't work, attached is the *.vect file.

does making int a[N]; aligned fix it? That is
int a[N] __attribute__((aligned(16)));
?

The long only shows:

nothing else.

Ok on a third bootstrap I can still reproduce, is there a way to debug it?
