Ned Deily added the comment:

What platform are you running on? Please run the following script in the same 
environment as you get the segfault and report the results.

#!/usr/bin/env python

import multiprocessing
import platform
import sqlite3
import sys

print(sys.version)
print(sqlite3.version)
print(sqlite3.sqlite_version)
print(multiprocessing.__version__)
print(multiprocessing.cpu_count())
print(platform.platform())

For what it's worth, I was not able to reproduce this behavior using several 
different environments.  Also, what happens if you add

    pool.close()
    pool.join()

following the pool.map call?
