component_index buffer overrun and segfaults

Description
The component_index routine segfaults when computing components over large input on msvc-8.0.
Quoting Jeremiah "Valgrind did show a buffer overrun in the code, and I added asserts and showed that it writes beyond the end of a temporary array, so it is definitely a bug in component_index".
Attached is the code and a sample dataset on which the component_index fails.
