Unbounded recursion in GetDatabase() when parsing include files [CVE-2013-2004 1/2]
GetIncludeFile() can call GetDatabase() which can call GetIncludeFile() which can call GetDatabase() which can call GetIncludeFile() .... eventually causing recursive stack overflow and crash. Easily reproduced with a resource file that #includes itself. Limit is set to a include depth of 100 files, which should be enough for all known use cases, but could be adjusted later if necessary.
