The problem turns out to be related to the recent update of libgd3. 
Reverting to the previous version fixes it.

Notice that cygMagickCore-6.Q16-2.dll, which occurs in the error dialog 
above, depends on cyggd-3.dll:

$ cygcheck /usr/bin/cygMagickCore-6.Q16-2.dll | grep cyggd-3
       C:\cygwin\bin\cyggd-3.dll

Marco, is it possible that the libgd3 update requires a rebuild of 
ImageMagick?
