Comment (by robe):

 FWIW My Mingw-w64 build Windows seems fine. So not all windows, assume
 just VC++ compiled and possibly specific versions.


 {{{
 POSTGIS="3.1.0alpha3 3.1.0alpha2-164-gd2d5c9f98" [EXTENSION] PGSQL="130"
 GEOS="3.9.0-CAPI-1.14.0" PROJ="7.1.1" LIBXML="2.9.9" LIBJSON="0.12"
 LIBPROTOBUF="1.2.1" WAGYU="0.5.0 (Internal)"
 }}}

 Using GEOS as of yesterday branch (also tested with one from a month ago).


 {{{
  SELECT ST_AsText(ST_SimplifyPreserveTopology(
      'MULTILINESTRING((0 0, 50 0, 70 0, 80 0, 100 0), (0 0, 50 1, 60 1,
 100  0))', 10.0));

 }}}

 yields consistently


 {{{
 MULTILINESTRING((0 0,100 0),(0 0,50 1,100 0))
 }}}
