Hum, this one is really tricky. It's indeed an aliasing problem and I think
your reduced, reduced testcase demonstrates that there might be a hole in the
flow-insensitive alias analysis for pointers that escape but are neither
explicitly dereferenced nor passed as explicit arguments to a function. I'll
ask the powers that be about this.
