Hi all,

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?

Or maybe the issue is that the latest build of gd should have had an ABI
bump.  Volker?

It seems more a libgd3 build problem.
Specially if it happens only on 32bit and not on 64bit.

The difference between 32-bit and 64-bit is due to differences in ImageMagick on the two platforms.

On 32-bit, as I showed in an earlier message, I get:

$ objdump -p /usr/bin/cygMagickCore-6.Q16-2.dll
[...]
        DLL Name: cyggd-3.dll
        vma:  Hint/Ord Member-Name Bound-To
        48ee2c      8  WebPDecode
[...]

On 64-bit, I get:

$ objdump -p /usr/bin/cygMagickCore-6.Q16-2.dll
[...]
        DLL Name: cygwebp-5.dll
        vma:  Hint/Ord Member-Name Bound-To
[...]
        48096c    271  WebPDecode
[...]

Moreover, libMagickCore6_2 depends on libgd3 on 32-bit but not 64-bit. So it seems that ImageMagick needs to be rebuilt on 32-bit so as to remove this dependency.
