Is that from a fresh Cython install? I.e. do you use an up-to-date build of
the compiled modules in Cython? I just want to make sure we are not hunting
a bug that's already fixed.

You can also install Cython uncompiled (i.e. pure Python) by passing the
"--no-cython-compile" option to setup.py. That will prevent any C level
crashes of the compiler itself. If you still want good performance,
deleting individual C modules (such as the crashing
Cython/Compiler/Parsing.so in your case) will make Cython fall back to the
normal Python modules that are installed in parallel.
