I wasn't able yet to get a nice testcase, the one attached has about 1000
lines. I am autoreducing other failures to see if there will be any suitable
for manual reduction...

Output:
$ g++ -m32 -std=gnu++0x -O2 -fno-early-inlining -fipa-pta testcase.C -w
$ ./a.out 
a.out:

I suspect this might be the same as PR47896, so don't spend too much time
here until that is fixed.

Jens, I think you meant to attach this to PR65641, but as I said there, unless
you have a copyright assignment we can't use it anyway.
