Hi, I'm converting CMYK tiffs to PNGs and using the embedded clipping path in the TIFF to create transparency in the PNGs.
I'm using the command:
convert test.tif -profile srgb.icc -colorspace rgb -fill white -draw "color 0 0 reset" -transparent white -clip -draw "Image Copy 0,0 0,0 test.tif" -geometry 200x200 test.png
It works great on 32bit machines (Linux or FreeBSD), but it fails strangely on any 64bit machine I've tried it on.
You can find some example files, named by the platform, IM version and if it's broken or not, here:

Is this a known bug? Has it been fixed in a later version (I couldn't find any reference in the ChangeLogs) ?
Thanks!
