PS: Segmentation faults only with linux we had last year with a former
version of alliance (cad of vlsi circuits). The problems came from wrong
deallocation of linked lists. Under SunOS-4.1.3 almost incredible wrong
deallocation schemes did not lead to errors. Linked list where
deallocated by first freeing structures and then evaluating the
list->next pointers (at a time where the memory was no more valid). It
worked absolutely relyable. We suspect since them that free() is only a
empty function (simple return) on some workstations:-). Also the memory
consumption of "perl" leads to this assumption.
