This problem requires two small patches. In magick/cache.c/QueueAuthenticNexus(), change

Code: Select all

  assert(cache_info->signature == MagickSignature);
  if (cache_info == (Cache) NULL)
    return((PixelPacket *) NULL);

to

Code: Select all

  if (cache_info == (Cache) NULL)
    return((PixelPacket *) NULL);
  assert(cache_info->signature == MagickSignature);

and in magick/montage.c/MontageImageList(), change

Code: Select all

    montage->columns=bounds.width;
    montage->rows=bounds.height;

to

Code: Select all

    montage->columns=MagickMax(bounds.width,1);
    montage->rows=MagickMax(bounds.height,1);

Will be these patches merged into main code of ImageMagick?

Thanks.

[magick]

The patches are already in Subversion for ImageMagick 6.7.2 and will be part of the ImageMagick 6.7.2-2 release within a week.
