MultiIndex DataFrame to_csv() terminates python process
#### Code Sample, a copy-pastable example if possible

```python
import traceback
import pandas as pd

# index is actually a MultiIndex
index = pd.Index([(1,), (2,), (3,)])
data = pd.DataFrame([[1, 2, 3]], columns=index)
data = data.reindex(columns=[(1,), (3,)])

try:
    # This call fails with a TypeError.
    data.to_csv('crash.csv')
except TypeError as err:
    traceback.print_exc()

# This print seems to be essential to trigger an immediate crash of the process
# in the following .to_csv call. The crash happens also if the preceding
# try/except block is removed.
print(data)
data.to_csv('crash.csv')
```

#### Problem description

The python-code above shows two, maybe three errors.
(1) The first call to DataFrame.to_csv raises a TypeError. This it uninformative at best. Printing the DataFrame works, so it should be possible to export it to csv. 
(2) The second call to DataFrame.to_csv leads to terminating python with exit code -1073741819 (0xC0000005). 
(3) It seems that the print call triggers this crash, even though I would expect a print to not alter the printed data structure.

The Windows event log shows an error happened in lib\site-packages\pandas\_libs\writers.cp36-win_amd64.pyd.

#### Expected Output

Because the DataFrame is printable on the console, I would expect a successful call of to_csv().

#### Output of ``pd.show_versions()``
