css_to_xpath mem leak with non ascii selectors

[Kovid Goyal]

python -c "from lxml.cssselect import css_to_xpath; print css_to_xpath(u'.test\u201d')"

This causes a massive memory leak on windows and OSX but correctly raises an exception on linux.

Windows versions:
Python : sys.version_info(major=2, minor=7, micro=1, releaselevel='final', serial=0)
lxml.etree : (2, 3, 0, 0)
libxml used : (2, 7, 7)
libxml compiled : (2, 7, 7)
libxslt used : (1, 1, 26)
libxslt compiled : (1, 1, 26)

This is using the lxml package from PyPI

I wouldn't know why this should be system specific. In any case, note that cssselect is currently becoming its own project, so this won't be fixed in lxml anymore. lxml will start to use the separate cssselect in the future.
