[Cython] Compiler crash in RemoveUnreachableCode

[Andriy Kornatskyy]

The cython compiler crash report below. Steps to reproduce:

1. virtualenv env
2. env/bin/easy_install cython
3. env/bin/easy_install wheezy.http

The wheezy.http has dependency on wheezy.core. If I install those two packages separately there is no error, only if through dependencies.

Thanks.
