[Live-devel] Event loop and threads

Ok, so now I added a static dummy method to my class , that gets the
UsageEnvironment* as argument, since it's not a global variable but an
attribute of that same class (same as the watchVariable).
Then, from another method where I call doEventLoop (the threaded
method of the class), I added the call to the dummy task:

dummyTask(this->Env);
this->Env->taskScheduler().doEventLoop(&(this->stopServer));

Well, with that call there, I get a SEG FAULT. Looking at the the last
stack frames:

inside AlarmHandler::handleTimeout, fClientData == 0x0
inside dummyTask, env == 0x0
inside UsageEnvironment::taskScheduler, this == 0x0

;before that everything seems normal. If I remove the call to
dummyTask, everything works fine.

Do you know what could it be?

Thanks!
