Working on the MinGW build I've progressed quite far but run into 
trouble with DLL loading. The problem seems to be related to OSR.

I've built the Perl bindings and another Perl interface to another C 
library, which uses GDAL and GTK+. It seems that something happens when 
the other Perl interface loads GDAL and GTK+ that makes it impossible to 
load OSR.

I'm using Dependency Walker, which shows which DLLs get loaded etc. In 
Perl the initialization is done by calling "use Module".

use Geo::OSR;
is ok as a program, GDAL (and GEOS) get loaded fine.

use Geo::Raster;
is ok as a program, GTK+ and GDAL get loaded fine (output 1).

use Geo::Raster;
use Geo::OSR;
is not ok, Access violation happens in NTDLL.DLL (in A_SHAFinal) (output 2).

Any ideas would be welcome. Is there something in the GDAL/OSR/OSR Swig 
bindings that would cause this? Am I right in thinking that the problem 
is related to OSR / GDAL? Maybe GTK+ screws up something? Any ideas how 
to see inside NTDLL.DLL?

Cheers,

Ari
