Dear Maintainer, I am seing the same behaviour...
It works fine with ghostscript 9.20: 11:18 user@machine ~ % ghostscript -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 '-sOutputFile=test.png' '-ftest.pdf' GPL Ghostscript 9.20 (2016-09-26) Copyright (C) 2016 Artifex Software, Inc.

Page 1 but fails with the latest version of Ghostscript that just landed in security: 11:19 user@machine ~ % ghostscript -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 '-sOutputFile=test.png' '-ftest.pdf' GPL Ghostscript 9.26 (2018-11-20) Copyright (C) 2018 Artifex Software, Inc.

Page 1 zsh: segmentation fault ghostscript -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 This has been replicated in at least 2 machines running Debian Stretch on my side. Of note, this is also treated for Ubuntu here: https://bugs.launchpad.net/ubuntu/+source/ghostscript/+bug/1806517 This regression is hurting the use of imagemagick on PDF files in production which is a severe regression. Temporary fix is to revert to a previous (but unsecure presumably) GS verion. Thank you for your help Pierre-Alain
