Test case reduced from libreoffice's shapeattributelayer.cxx

Here is an assertion encountered by Michal Meloun, while compiling
LibreOffice's slideshow/source/engine/shapeattributelayer.cxx file for
armv7-freebsd:

Assertion failed: (!NodePtr->isKnownSentinel()), function operator*, file
include/llvm/ADT/ilist_iterator.h, line 139.

Attached is a reduced test case, to be compiled with:

clang -cc1 -triple armv7 -S -O2 lo.cpp

Specifically, the 'armv7' is important, just 'arm' or 'armv6' will not trigger
the assertion.
