This appears to have been introduced way back in 2004:

 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=b221d046 [^]

The "while ( path.size() > dir.size() );" code assumes that eventually the parent directory will be shorter, but "C:/" is never shorter than "/".

Fixed in upstream KWSys here:

 http://public.kitware.com/gitweb?p=KWSys.git;a=commitdiff;h=beef6819 [^]

and integrated into CMake here:
