[m-users.] seg fault, 64 bit

[Tomas By]

Hi again,

I have now determined that this problem is caused by passing a string
containing non-ascii characters to a predicate defined as a fact table (as
(string::in) is semidet).

Is this a know error? There doesn't seem to be any mention in the manual.

/Tomas
