simple example app

Runtime crash can occur when modules built with -frtti and -fno-rtti are linked
into a single app. Basically, we get two different definitions of
std::bad_function_call and the discrepancy in memory layout can cause a crash.
See attached example. It's very simple, only two functions and a script to
build it. See also additional notes about link order in that script
'makeAndRun'.</pre>
