Comment(by strk):

 I think the solution here would be to make available (at least at the
 liblwgeom level) a more robust line location computer that reports
 distance on a local segment rather than on the whole line. This would be a
 pair composed by vertex index _and_ distance from the vertex. Any exact
 vertex would have a distance of 0, for full robustness of those cases.
