Runtime error when writing file on windows (mingw)

[mmickey]

Hi folks,
I use ImageMagick-6.5.6-10 for Windows (self compiled) with mingw.
When I try to save an image with

Code: Select all

image.write(FileName);

I get an runtime error and my program crashes. The error is precisely at this call. Before the error the file is saved.
The same code works perfectly with linux.
Any ideas?
Thanks for your help.

greets mike
