This sounds strangely familiar. I had lots of trouble with initialization
code that was due to the undefined order of global variable initialization.
We eventually replaced all global variables (in synopsis) by alternatives
(singletons, explicit initialization, etc.) and the problem disappeared.

May be there are somewhere some global variables left in opencxx...
