[XeTeX] scshape + scriptsize + Charis SIL = segmentation fault

[Marcin 'Qrczak' Kowalczyk]

The following document causes xetex-0.996 to crash:

\documentclass[a4paper]{article}
\usepackage{fontspec}
\setmainfont{Charis SIL}
\begin{document}
\textsc{\scriptsize abc}
\end{document}

BTW, small caps don't work for all fonts I checked (except Latin
Modern). Do they require special support in the font?
