Add the following line to Condition::Condition() in condition.cc:
printf("Constructor: Condition %p (%s)\n",(void*)this,this->getName());
Add the following line to Condition::~Condition() in condition.cc:
printf("Destructor: Condition %p (%s)\n",(void*)this,this->getName());
Go to condition.cc, Condition::timedWait() and change the first line "result
=
pthread_cond_timedwait(&ConditionVariable,&Mutex,&timeout);"
to:
puts("TimeWait1...");
result = pthread_cond_timedwait(&ConditionVariable,&Mutex,&timeout);
puts("TimeWait1 ok");
. Change the second line of "result =
pthread_cond_timedwait(&ConditionVariable,&Mutex,&timeout)" to:
puts("TimeWait2...");
result = pthread_cond_timedwait(&ConditionVariable,&Mutex,&timeout);
puts("TimeWait2 ok");
Add "printf("Fired set to false for condition %p
(%s)\n",(void*)this,this->getName());" after "Fired = false;".

Now, recompile the sources and send me the output. Are you absolutely sure
that the thread settings (-D_REENTRANT -pthread) for the compiler are set for
all your files? What are your optimization options (e.g. -O2). Try to set
them to "-O0".

Can you reproduce the problem under Linux? If yes, go to
http://developer.kde.org/~sewardj/ and download the memory debugger Valgrind.
Then, check your program with the options "-v --leak-check=yes
--show-reachable=no --leak-resolution=high --num-callers=40" to ensure that
your program does not destroy structures of the sctplib, socket API or
rsplib.
