We use ImageMagick to extract a the first page of a PDF as a thumbnail and recently started getting exceptions with some PDFs. Traced it to the call that ImageMagick was making:

gs -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r72x72' -dLastPage=1 -sOutputFile=1.png -f Bloomfire-Security_and_Redundancy.pdf

When this is run with GS version 9.25, the thumbnail is extracted with no error.
When this is run with GS version 9.26, I see "Segmentation fault: 11"

I've attached a file that causes there error. Observed on both OSX and Ubuntu Linux.
