Abort trap: 6 after upgrade to 6.9.9-40 Q16 x86_64

Hi all,

I am running Macos 10.14.5 (18F132), and have installed Imagemagick via Macports. I have recently upgraded to version 6.9.9-40 Q16 x86_64. The full output for 'convert -version' reads:

Version: ImageMagick 6.9.9-40 Q16 x86_64 2019-06-11 http://www.imagemagick.org

I have a script for batch converting PDF files to PNG files, which goes:

Code: Select all

for i in *.pdf; do convert -verbose -density 600 -trim $i -quality 100 -flatten $(basename "$i" .pdf).png;done

After I upgraded to the latest version of Imagemagick, this no longer works. I get an 'Abort trap: 6' for each file in the batch. Sample output reads:

[ghostscript library 9.27] -sstdout=%stderr -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r600x600' '-sOutputFile=/var/folders/k0/m6mz3d055m75782ynnkt2k0w0000gn/T/magick-5910MkmWy1yIM0tx%d' '-f/var/folders/k0/m6mz3d055m75782ynnkt2k0w0000gn/T/magick-5910gs9cNcP8C7cU' '-f/var/folders/k0/m6mz3d055m75782ynnkt2k0w0000gn/T/magick-5910iJZ-CiPdfIWp'Abort trap: 6

This isn't restricted to this script, Imagemagick also returns this error when I try to run a simple conversion (no attributes whatsoever) of one PDF file into PNG.

Best,

Your "-trim" should be after reading the PDF, not before. (But that won't cause an abort.)

Recent Ghostscript seems to have problems. I suggest you downgrade to 9.25 or earlier.

I have heard issue with both GS 9.26 and 9.27. So downgrade to 9.23-9.25 as suggested by snibgo.

I'm not sure, but I think that the issues I am experiencing might have to do with Ghostscript looking for certain X11 related dylib files in the wrong place.

I have located the Ghostscript executables on my filesystem. There are two execs, one called 'gs-noX11', and one called 'gs-X11'. When I run the 'gs-X11' exec, I get the same error message as I get when trying to convert PDFs to PNGs with the batch script I mentioned above. Output upon running 'gs-X11' reads:

/usr/local/bin/gs-X11
dyld: Library not loaded: /opt/X11/lib/libXt.6.dylib
Referenced from: /usr/local/bin/gs-X11
Reason: image not found
Abort trap: 6

It's true that 'libXt.6.dylib' is not in the folder which Ghostscript is trying to find it in. Instead of '/opt/X11/lib/', this dylib is in '/opt/local/lib' on my filesystem. Does anyone know how to point GS to the correct folder? That would be easier than downgrading to an earlier version of Ghostscript, as, annoyingly enough, I removed the old version of Ghostscript from my port directory right after I upgraded.

Nevermind, I just downgraded to GS 9.26 (easier than I thought) and everything is working as it should again.
