[postgis-users] Win32 PostgreSQL 7.5/PostGIS snapshot availablefor developers

[Mark Cave-Ayland]

Hi Tyler,

I must admit I hadn't seen the index bug since I had only used a few
geometries in a table for my tests, but I was able to recreate it by
generating a large file full of random geometries and trying to build an
index on that as you suggested.

I've done some debugging using gdb and it looks like one of the GiST
pointers being passed into one of the GiST routines is wrong, so it's a
PostgreSQL/Win32 issue. I've submitted a suitable bug report to the
Win32 people along with my offer of help, and so I don't think it will
be too long before this issue is resolved. I'll keep the list posted
with my progress on this.


Many thanks,

Mark.
