small program illustrating crash

I've struggled to pare this bug down to a smaller example but noticed that 
invocation of a thread_local random number generating functor in GCC 4.8.1
caused a regular, though not always reproducible, crash that I did not see in
Clang 3.3.

Both thread_local and use of std::bind seem to be necessary to reproduce the
crash.

Code was compiled with -std=c++11
