Comment 0 for bug 1558076

The following code randomly crashes Python interpreter (both 2.7.6 and 2.7.11 versions) on Windows 8:

from bs4 import BeautifulSoup

with open('page.html', 'r') as f:
    content = f.read()
    for i in xrange(1000000000):
        print(i)
        soup = BeautifulSoup(content, 'lxml') # 'html.parser' and 'html5lib' parsers works perfectly

As I stated in the summary of this bug, the crash happens only on certain pages, so I attached an example of such file to this report.

==================================

There's no additional output in stdout / stderr so the only information I have at the moment is the standard error info from the corresponding Windows dialog (note that the Fault Module Name is "lxml.etree.pyd"):

==================================

Moreover I noticed that the following code doesn't crash at all:

from lxml import etree

with open('page.html', 'r') as f:
    content = f.read()
    for i in xrange(1000000000):
        print(i)
        tree = etree.HTML(content)

I know that there must be some error in BeautifulSoup library then but I think that the incorrect usage of lxml should not crash an interpreter anyway.

==================================

lxml versions -- 3.4.4 and 3.5.0
BeautifulSoup version -- 4.4.1 (the latest one at the time of writing)
