Thanks Matt. That may come in handy.

Below is what I am seeing. I'm looking for more detail at "32732:
initialize program: ./cryptest.exe". I want to see the symbolic name
of each object created, and the order in which it was created. For
example,

     32732:    initialize program: ./cryptest.exe
     32732:    initializing std::string DEFAULT_CHANNEL
     32732:    initializing std::string AAD_CHANNEL
     ...
     32732:    initializing Foo g_bar
     ...

Is that possible to do?

If not, how do folks tell that init_priority is being honored? And if
init_priority in not in effect, how can we tell the order of object
creation?
