When running with -DENABLE_PERFORMANCE_COUNTERS I setup a simple graph
including "Control Port Monitor" and "Performance counters". When I run the
graph I get a general protection page fault in the code that calls
rpcmanager::get(). Turns out rpcmanager::get() returns NULL. It looks like
the library (libgnuradio_runtime.so) is getting initialized and the code below
is called setting up the 'boot' static structure:
gnuradio-runtime/lib/controlport/rpcmanager.cc
bool rpcmanager::booter_registered(false);
bool rpcmanager::aggregator_registered(false);
std::auto_ptr<rpcserver_booter_base> rpcmanager::boot(0);
std::auto_ptr<rpcserver_booter_aggregator> rpcmanager::aggregator(0);
but then the 'init' function for the shared library gets called again which
zeros out the boot pointer.
This is the first time the boot pointer initializes.

The is the second time the shared library init gets called zering out the boot
pointer.
