Situation is following. I have shared library, which contains class definition -
QueueClass : IClassInterface { virtual void LOL() { do some magic} }
My guess is that GCC is taking the opportunity to inline the call to LOL. I'll see if I can find a reference for you on this...
I see sechastain beat me to a more thorough description and I could not google up the reference I was looking for. So I'll leave it at that.
