Yeppers: the reason is, that in the older circle versions, signed values
were used for flags, that means, that the first bit served as a minus
or plus, marking the number as positive/negative. If you set that bit,
the number turns negative, resulting in an invalid bitvector. The
solution: in one of the last patches, there were changes, introducing
a bitvector_t type, which is an unsigned long in stock circle, and can
be adjustet as needed (e.g. unsigned long long or so). This change
uses unsigned values, so that negative numbers are no longer possible.

Try to look at the patches, however I'm not sure which one it was,
maybe 13 -> 14, and hand-patch your code with them. Take care
with your pfiles however, so you had better first test it out.
