When building agent++ with VC++ 6.0, I receive the following warning:
TaskManager::TaskManager(ThreadPool *tp, int stackSize):thread(*this)
c:\agent\src\threads.cpp(660) : warning C4355: 'this' : used in base member
initializer list
I haven't looked to see whether any actual harm is being done in this particular
case, but in general it's a very bad idea to use a non-existant object in a
constructor. (The point being that at the time that the thread() constructor is
called, it is called with a parameter that is a derived object that does not yet
exist. I believe that this is at best non-portable, and at worst could be fatal
at run-time.)
