ImageMagick @6.9.9-40_5: convert crashed when converting pdf to png

[pgee70]

Hi Been using imagemagick/convert for years. I have been running automated tests.

After upgrading to version ImageMagick 6.9.9-40 i get an error when running the image magick convert command. Abort trap: 6

on converting an image that had previously worked using older versions.

I note that this is not the most recent version of imagmagic, also i don't appear to be able to downgrade to an earlier version using ports.

the same command works fine on ubuntu using Version: ImageMagick 6.9.7-4 Q16 x86_64 20170114

I can confirm the crash when running the command you provided (though a more basic convert test.pdf test.png works).

I've been meaning to update ImageMagick to the latest version of 6.x. But because the library versions change, it means I have to identify and revbump all the ports that link with those libraries, which is tedious and time-consuming.

I can confirm the same behaviour when converting a PDF to any of PNG, JPEG, and GIF. I did some digging and found that convert is failing to delete a temporary file under /var/folders (see attached debug log). I’m not sure whether this is because the file no longer exists or some other reason, but it looks like the former (the file is definitely not there after the fact). The temporary files it’s creating appear to be symlinks to the source image(s) being converted.

The problem is definitely in convert — I used convert -verbose to extract the generated GhostScript command and that worked fine.

This broke one of my video processing tools (see ​https://github.com/nstanger/process_podcast/issues/36) so it’s good to see that there is at least a ticket open for it.

Version 7 seems just fine on linux for the same file

Can we get the Version 7 installed ?

I built Imagemagick from source and convert works on macOS 10.14

If this helps I built it using dir=/usr/local

Same problem here. After moving to Catalina I upgraded my MacPorts to darwin19. Reinstalled imagemagick using port install

ImageMagick-6.9.9-40_6+rsvg+x11.darwin_19.x86_64.tbz2 from ​https://packages.macports.org/ImageMagick

Xcode 11.2
Apple clang version 11.0.0 (clang-1100.0.33.12)
Target: x86_64-apple-darwin19.0.0
Thread model: posix

Example of call:

convert woa13_density_compr_0.25.eps woa13_density_compr_0.25.png
Abort trap: 6

worked perfectly before on darwin18

ImageMagick 7 is not in MacPorts yet. See #51310.

[ryandesign (Ryan Carsten Schmidt)]

It would be good if someone could attach a crash log. But the first step we should probably take is updating ImageMagick to the latest 6.x version. See #57903.

Is this different from the convert -debug log I attached a few months back (convert_debug.txt​)? If so, what would you prefer and how do I generate it?

[ryandesign (Ryan Carsten Schmidt)]

Yes. Whenever a program crashes, macOS writes a crash log to Library/Logs/DiagnosticReports/.

Aha! Easy :). See attached, the command was convert blank.pdf blank.png (I’ve also attached the PDF).

It looks like a problem with Ghostscript:

9   ???                                 0x0000ffff00001fa0 0 + 281470681751456
10  libgs.9.27.dylib                    0x000000010e5ada59 gs_malloc_init_with_context + 34

From the Ghostscript library's gs_malloc_init_with_context function it tries to jump to an unreasonable memory address.

This has also been reported as #58595.

[ryandesign (Ryan Carsten Schmidt)]

Looks like as of Ghostscript 9.27, a change is needed in ImageMagick when initializing Ghostscript. We need to update to ImageMagick 6.9.10-71 6.9.10-39 or later to get the fix.

[joostdekeijzer (joost de keijzer)]

For me, as a quick fix, downgrading Ghostscript to v9.26 works fine. See wiki:howto/InstallingOlderPort for the howto.

When building from source you'll need to checkout commit af11993aab38d7ba77c2df895aa5ce9b405c5681

Handy workaround, thanks!

The Ghostscript port was recently updated to 9.5, but still dies in the same way (as I pretty much expected).

And #57903 is about getting that update done.

[ryandesign (Ryan Carsten Schmidt)]

ImageMagick has been updated to 6.9.10-71 and should no longer have this bug. If you had downgraded ghostscript to 9.26 to work around this bug, remember to reactivate ghostscript 9.50 before upgrading everything else.

Replying to ryandesign:

ImageMagick has been updated to 6.9.10-71 and should no longer have this bug.

Yes! Working correctly now. Thanks!
