 Confirmed with:
 {{{
 POSTGIS="2.1.4 r12966" GEOS="3.6.0dev-CAPI-1.10.0 r4208" PROJ="Rel. 4.8.0,

 LIBJSON="UNKNOWN" RASTER

 The problem is in GEOSUnaryUnion, so worth filing a ticket in GEOS too:
 https://trac.osgeo.org/geos

 It's worth to point out that GEOS has a GEOSNode function since version
 3.4.0, but PostGIS is not using it. Would be worth a test against this
 case.
