[postgis-devel] raster regression failures

[Greg Troxel]

I get two failures on the raster regression tests with:

  PostGIS is now configured for i386-unknown-netbsdelf5.1.

 -------------- Compiler Info ------------- 
  C compiler:           gcc -g -O2
  C++ compiler:         g++ -g -O2

 -------------- Dependencies -------------- 
  GEOS config:          /usr/pkg/bin/geos-config
  GEOS version:         3.3.2
  GDAL config:          /usr/pkg/bin/gdal-config
  GDAL version:         1.8.0

 --------------- Extensions ---------------

  PostGIS Topology:     enabled

 -------- Documentation Generation -------- 
  xsltproc:             /usr/pkg/bin/xsltproc
  xsl style sheets:     /usr/pkg/share/xsl/docbook
  dblatex:              
  convert:              /usr/pkg/bin/convert


The diffs follow, but basically I seem to get NaN instead of a value.  I
ran "paranoia"*, which when compiled with -ffloat-store was totally happy
with my compiler/library/processor's arithmetic.  So, while realizing
that my results seem off, I wonder if

  anyone else sees this

  if the tests assume i386 extended double registers

  if the tests are known to pass on non-i386 (eg. sparc64) with a
  different floating point implementation

  anyone has any other clues


I will update gdal and retry, but 1.8.0 is >= 1.6.0 which is documented
to work.
