Confirmed here too, on 3.0.0 but not 2.4, 2.5, or cb-3.0.1.

No way to know if a source mod fixes it then...

I had a quick hack and it appears to be crashing on my system in routine
restore_privates, in the code:

        // restore the current task's private data (will always be there)

        block = load_private_block(this_routine, current_task);

        // private vars
        sym = this_routine->next;
        while (sym != NULL && sym->scope <= S_PRIVATE) {
            sym->obj = *block++;
            sym = sym->next;
        }

it crashes on the sym->obj = *block statement. A chunk of heap ends at #004D5FFF
and when it crashes block is #004D6000. sym is correctly pointing at the
parameter r. I have not studied load/save_private_block, but that is where my
suspicions would lie. A random thought I had is that if it were saving and
loading everything out-by-one, it might well appear to work fine in 99.9% of
cases. Or maybe not.
