Bug description:
In order to convert a PDF file in PNG I use the command:
» convert "myfile.pdf[0]" test.png
Which gives this error:
convert-im6.q16: FailedToExecuteCommand `'gs' -sstdout=%stderr -dQUIET
-dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0
-dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4
'-r72x72' -dFirstPage=1 -dLastPage=1
'-sOutputFile=/tmp/magick-11774WIkYdVETEs9I%d'
'-f/tmp/magick-11774JZhknqCDhkN0' '-f/tmp/magick-11774twGtf-JFihri'' (-1) @
error/delegate.c/ExternalDelegateCommand/462.
convert-im6.q16: no images defined `test.png' @
error/convert.c/ConvertImageCommand/3258.
So I tried using ghostscript directly:
» 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' '-fmyfile.pdf'
Which gives an error:

If I omit -dFirstPage=1 -dLastPage=1 it works properly:
» ghostscript -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000
-dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4

Please note that it also affects imagemagick convert command and PHP
readimage command. I have confirmed the bug on Ubuntu 16.04 too.
The recent ghostscript 9.26 version is definitely guilty.
