In Symbian OS 8.1b, 9.0, 9.1 and subsequent versions:
this panic is raised when an exception is raised on the
current thread by a call to User::RaiseException(), and
the thread has no exception handler to handle the specified exception.
In Symbian OS up to 8.1a:
this panic is raised when the current thread calls
RThread::RaiseException() on itself, and the thread has no
exception handler to handle the specified exception.
Note that the RThread::RaiseException()
API is deprecated in Symbian OS 8.1b, 9.0, 9.1 and subsequent
versions, and should not be used.
