[c++] Eclipse CDT parser bugs with firefox codebase

Repo: https://github.com/mozilla-firefox/firefox

Getting a number of crashes similar to the one below. These need to be reported and fixed upstream, unfortunately.

Exception occurred while processing AST for file: /home/appthreat/sandbox/firefox/gfx/src/FilterSupport.cpp after parsing: Cannot invoke "org.eclipse.cdt.core.CCorePlugin.getLog()" because the return value of "org.eclipse.cdt.core.CCorePlugin.getDefault()" is null - org.eclipse.cdt.core.CCorePlugin.log(CCorePlugin.java:1612)

Needs retesting with the latest.
