I'm running the XTS (http://cgit.freedesktop.org/xorg/test/xts/) test
suite against Xvnc. The XDrawArc crashes the server every time. This
happens with both our own build (using xserver 1.5), as well with the Xvnc
shipped with Fedora 14. For some unknown reason, I'm not getting any core
dumps from the F14 Xvnc, but from our build, I've retrieved this
backtrace:
