[postgis-users] extent buffer issue

["R. Müller"]

hi to all,

the following test-case produces a floating point exception on my box:

select buffer(extent(geomfromtext('Point(1 1)',-1)),1);

the exact error message is in german (sorry for that):

FEHLER:  Fliesskommafehler
DETAIL:  Eine ungueltige Fliesskommaoperation wurde signalisiert. Das 
bedeutet wahrscheinlich ein Ergebnis ausserhalb des gueltigen Bereiches 
oder eine ungueltige Operation, zum Beispiel Division durch null.

and means (freely translated) :
ERROR : floating point exception
DETAILS : an invalid floating point operation was detected. which 
probably means that a result is out of valid range or invalid operation, 
  for instance division by zero.

my postgis-version is :
POSTGIS="1.1.0CVS" GEOS="2.2.2" PROJ="Rel. 4.4.9, 29 Oct 2004" USE_STATS 
DBPROC="0.3.1" RELPROC="0.3.1"'

my postgresql-version is :
PostgreSQL 8.0.8 on x86_64-pc-linux-gnu, compiled by GCC 
x86_64-pc-linux-gnu-gcc (GCC) 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, 
pie-8.7.9)

my box is :
Linux 2.6.10 #2 SMP Tue Feb 15 14:14:46 CET 2005 x86_64 AMD Athlon(tm) 
64 Processor 3500+ GNU/Linux

does anybody know this issue ?

regards

ronald
