I am using Window 7 64-bit. After installing the ImageMagick-6.6.9-3-Q16-windows-x64-dll.exe, the crashed and produced the empty b.png. The a.png is the snapshot of the application window
and can be downloaded from http://www.skil.cz/bug/ImageMagick/a.png

The same problem was observed with the 32-bit version of the ImageMagick version (the same release).
After returning back to ImageMagick-6.6.3-4-Q16-windows-x64-dll.exe it work (almost) fine.

My reason for the wanted update was that the older version complains about
invalid background palette index when converting another file
The c.png can be downloaded as http://www.skil.cz/bug/ImageMagick/c.png

Thanks,
Petr

Both commands ran successfully (no crash) on my IM 6.6.9.3 Q16 Mac OSX Tiger. HOWEVER, neither resulting image could be opened.

I'm seeing a "double-free" crash with both commands on my
Ubuntu platform with IM-6.9.3 apparently during the quantization to the 3-3-3-1
palette. It is in a section of code where there is a comment "should not
reach this", so there's some kind of logic error there.

edit: The problem was that a bogus image->colormap was attached to
the non-PseudoClass image that was passed to the PNG encoder.
This is fixed (in the PNG encoder, not fixing the underlying problem) in SVN
revision 4193 (IM-6.6.9-4).

Thanks! The 6.6.9-4 works now
