Hi

After i upgraded to Imagemagick 6.5.5-2, certain Image gets corrupted in my production enviroment. The command I call is:

Code: Select all

convert 5653.tif +clip-path "#1" -fill white -draw "color 0,0 reset" out.tif

I get no errors, but the converted image has a fat wide white vertical line thats not supposed to be there.
I have tried to reproduce the error in our test environment, but everything works fine here. Could anyone give me any pointers to where i might look for the error? The Imagemagick is compiled almost identical in the two systems:

The conversion works fine on a number of our systems. We're using ImageMagick 6.5.5-6, the current release. We suspect your system may have a buggy libgomp used to support OpenMP. Disable OpenMP on your system and see if that fixes the problem:

cd ImageMagick-6.5.5-6
./configure --disable-openmp
make
make install

Hi

Thank you for the quick answer. I have recompiled the Imagemagic in production without openMp support, but i believe that it already was without openMP. The result was negative - the Image is still corrupted. I checked the GCC compiler on the two systems:

Prod: 4.1.2 (Suse 10.2)
Test: 4.3.3 (Ubuntu 9.04)

I then tried to disable openMP support in test (--disable-openmp) to make it look a bit more like the production version, but the Image is still fine in test.

Any more hints?

Update:

Another difference between the two systems is Libtiff:

Prod: libtiff.so.3.8.2
Test: libtiff.so.4.2.1

Could that make the difference?
