Hi Uwe,
I think it should be possible to create and resume a thread from a
static constructor, but you have to ensure that scheduler object has
been created before, otherwise the initiliazation of the scheduler
will overwrite the activation of your thread.
Ciao, Fabian

As soon as this object is created (it is the last one that is constructed cyg_hal_invoke_constructors()) it is not possible to view the list of threads from insight or GDB any longer. If I select View, Thread List in insight, I get an empty thread list or an error message that it was not possible to get thread list. If I remove this object from my application, then this problem does not occur.
