[postgis-users] Intersection doesn't work on some data

[strk]

This is what I get with postgis-CVS:

SRID=-1;MULTILINESTRING((-121.33193 41.18388,-121.34693 41.18388),
(-121.34693 41.18388,-121.36293 41.18388),(-121.36293 41.18388,
-121.36545 41.18388),(-121.36545 41.18388,-121.37179 41.18388),
(-121.37179 41.18388,-121.37608 41.18402),(-121.37608
41.18402,-121.44594 41.18385))

This is what you reported as the correct answer:

MULTILINESTRING ((-121.331929 41.18388, -121.34693 41.18388),
(-121.34693 41.18388, -121.36293 41.18388), (-121.36293 41.18388,
-121.36544 41.18388), (-121.36544 41.18388, -121.37179 41.18388),
(-121.37179 41.18388, -121.37608 41.18401), (-121.37608
41.184019, -121.44593 41.18384))

There is a 0.00001 displacement, but I think the bug you reported 
has already been fixed. What version of postgis are you running ?
