Comment(by strk):

 Wonders, it's not ST_Snap but our nice splitting functions (LRS?):
 {{{
 DEBUG:  Intersecting nodes: MULTIPOINT(0 1)
 DEBUG:  Snapped to nodes: LINESTRING(0 1,0 1,0 1,0 1)
 DEBUG:  Split by POINT(0 1): MULTILINESTRING((0 1),(-nan -nan,0 1))
 DEBUG:  Split: MULTILINESTRING((0 1),(-nan -nan,0 1))
 }}}

 Then the NaN input kills something else...
