Comment(by robe):

 This doesn't seem to crash on my 2.1.0 9.2 64-bit windows:

 {{{
 PostgreSQL 9.2.2, compiled by Visual C++ build 1600,
 64-bitPOSTGIS="2.1.0SVN r11008" GEOS="3.4.0dev-CAPI-1.8.0 r0" PROJ="Rel.
 4.8.0, 6 March 2012" GDAL="GDAL 1.9.2, released 2012/10/08" LIBXML="2.7.8"
 LIBJSON="UNKNOWN" RASTER
 }}}

 Just gives error:


 {{{
 ERROR:  GEOSOffsetCurve: IllegalArgumentException: RobustDeterminant
 encountered non-finite numbers

 }}}

 so might be an already fixed bug in GEOS.
