From:

Clang is failing with an internal assertion failure, seems like it's not parsing something correctly in RenderSlider.cpp, and hitting EOF:

Assertion failed: (FieldNo < FieldCount && "Invalid Field No"), function getFieldOffset, file /a/portbuild/amd64/9-exp/builds/20110616185105/src/lib/clang/libclangast/../../../contrib/llvm/tools/clang/include/clang/AST/RecordLayout.h, line 121.

I don't see any potentially related bugs in llvm.org's bugtracker, so this might be a new one.  :-)
