Investigation showed the following inequality throws the exception:

(136.653830 , -638.496893) == (136.653830 , -638.496893)

which in hex looks like:

(406114EC2CAB84D2 , C083F3F9A32A10A6) == (406114EC2CAB84D2 , C083F3F9A32A10A7)

would it not be desirable to (instead) put some tolerance for round-off error into the 2geom routine, since the difference between these two points is clearly negligible ?

I second that. It's never a good idea to test two floating point numbers for equality. You should always have an epsilon to account for rounding errors.
