also seen on windows. here i'm testing on linux:

i'm convering these odd PDF files to JPG with these command line arguments: 
-dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -r150 -sDEVICE=jpeg -dJPEGQ=90 -dNumRenderingThreads=4 -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -sOutputFile=/tmp/page-%04d.jpg

and have been experimenting with and without the -dNOGC option (for a 10-20% speedup). but seems like there's a regression in 9.07:

case 1 with this file: http://sicnarf.com/wp-content/uploads/2013/04/verteiler_kw_16_2013.pdf
9.06: no problem
9.06 with -dNOGC: no problem
9.07: no problem
9.07 with -dNOGC: seg fault

case 2 with this file: http://sicnarf.com/wp-content/uploads/2013/04/crash_ghostscript_saturn_14_flash_v2.pdf
9.06: segfault
9.06 with -dNOGC: segfault
9.07: no problem
9.07 with -dNOGC: segfault
