Hi there,

Notification of a interpreter error.  The error is something like:
If a vector to be bonded (on either left or right) includes infinity (+ and/or 
-) and is longer than 7 items then interpreter returns NaN error.

However if vector is longer than 7 items the interpreter (cleverly) can 
sometimes optimise.
Eg   0 _ _ _ _ _ _ _ _ _   becomes  (_*i.10) and error does not occur.



J602  on win XP SP2.

7 appears to be the magic number for the length of the constant vector to bond.

The error also occurs when bonding with other functions (on both left and 
right).


Note I cannot use the wiki

as it won't let me reset the password - it says that recovery token (copied out 
of return email) is invalid.  Please let me know how to get into the system.
