fix_missing_locations(exprAst)
compiled = compile(exprAst, "<foo>", "single")
eval(compiled, {}, globalsDict)

f = globalsDict["Py_Main"]
print(f)
```

This outputs:
SystemError: Objects/codeobject.c:64: bad argument to internal function

PyPy 1.5 outputs:
<function Py_Main at 0x0000000103520610>

I'll try to reduce the test case a bit further.
