Boost Python - C++ class' private static data blown away before accessing in Python?

re.search much slower then grep on some regular expressions
What can be the cause of the large difference between re.search and grep? This script takes about 5 min to run on my computer: #!/usr/bin/env python import re row="" for a in range(156000): row+="a" print re.search('[^ "=]*/',row) While doing a simple grep: grep '[^ "=]*/' input (... 10 Jul 2008 13:24
