Package: graphicsmagick
Version: 1.4+really1.3.48-1
Severity: normal
Tags: upstream
Dear Maintainer,
The GraphicsMagick command fails when decomposing a (three or more) multiple
frames tiff image to multiple tiff images. For example:
gm convert -size 10x10 xc:black image1.tif
gm convert image1.tif image1.tif image1.tif image.tif
gm identify image.tif
gm convert image.tif +adjoin image_%04d.tif
leads to the output:
image.tif[0] TIFF 10x10+0+0 DirectClass 1-bit 860 0.000u 0m:0.000005s
image.tif[1] TIFF 10x10+0+0 DirectClass 1-bit 860 0.000u 0m:0.000039s
image.tif[2] TIFF 10x10+0+0 DirectClass 1-bit 860 0.000u 0m:0.000033s
double free or corruption (out)
gm convert: abort due to signal 6 (SIGABRT) "Abort"...
Aborted
even if the output images image_0000.tif, image_0001.tif and image_0002.tif are
properly generated.
This runs with no error when image.tif contains only two frames, and when
requesting a jpg output image_%04d.jpg
These commands run with no error with version
libgraphicsmagick-q16-3t64=1.4+really1.3.45+hg17696-1
Thanks,
Alexis Bienvenüe.
