core dump when converting pdf to tif

[TOP]

ImageMagick convert should exit gracefully instead of core dumping.

When using

Code: Select all

convert file1.pdf file1.tif

I get a core dump every time. I am able to convert the pdf to tif in gimp and then reverse the process back to pdf using convert.

Code: Select all

gimp file1.pdf

(work on file and export to file1.tif)

When I try to round trip the converted file, again there is a core dump.

Code: Select all

convert file1.tif file1.pdf
convert file1.pdf file1.tif

Core dump

Code: Select all

 convert -verbose file1.pdf file1.tif

You might try upgrading Ghostscript. Version 9.10 is rather old. It is at least at 9.21. Or post your PDF file and we can test. You can post to any free hosting service and put the URL here.

Its also likely that Ghostscript is core dumping rather than ImageMagick. An upgrade to Ghostscript may resolve the problem.

Hmmm. Core dumping is still impolite.

Ghostscript on it's own has no problem8 with the files in question. If it is ghostscript and it is is only choking on the pdf files (and these files contain only scan data) then it is still up to ImageMagick to check that GS is at least the right version, don't you think?

But I'll try and upgrade it if I can.

I'll also try and place (a) file(s) on an accessible file sharing service and post a link later.

Try upgrading IM to the latest version 7.0.5.6 and the latest GS (9.21?) or post your failing PDF. There was some problems creating PDFs recently, though your issue is the opposite.

This seems to suggest that your are using IM 6.7.7.10 and not IM 7.0.5.3. Do I misunderstand?

Might you have a conflict between two active versions of ImageMagick?

I installed a newer version of IM because I needed the hdri functionality to run retinex. Apparently I didn't remove the old version. Now trying to recompile it.
