Convert with TIFF64 delegate doesn't work with ImageMagick-7.0.3-8-Q16-x64-dll.exe but do with ImageMagick-7.0.2-7-Q16

Dear all,

I tried to convert large tif files (above 4GB). I work on cygwin under windows 7 x64 with ImageMagick-7.0.3-8-Q16-x64-dll.exe.
The command I use is:

convert infile.tif infile_scalebar.gif -background black -gravity center -append TIFF64:outfile.tif

Convert.exe can work on tif files above 4GB with version ImageMagick-7.0.2-7-Q16-x64-dll.exe. but don't with last version ImageMagick-7.0.3-8-Q16-x64-dll.exe. The outfile.tif started to be write but stop at 1.7GB. There is no problem with the previous version.
