ERROR: lxml.etree.XMLSyntaxError: internal error: Huge input lookup

[frakman1]

I get this error when analyzing a project with 3694 files. Is this a cppcheck issue or a code climate issue?
Since it happened within the cppcheck engine, I am raising it here.
Please advise.

Hi, I'm cppcheck contributor.
It seems that the error is not in cppcheck. We don't use lxml internally. Instead we use xml module from the standard library in addons. So, I suppose this is a codeclimate issue.
