Bug Description

gs chares while processing pdf by it's full path.

versions 8.71, 9.05 and 9.06 (pre-release freeze) are affected by this bug.

Expected: split first slide from pdf.

ghostscript -sDEVICE=pdfwrite -dNOPAUSE -dQUIET -dBATCH -dFirstPage=1 -dLastPage=1 -sOutputFile=/var/onlinestudios/recording/process/presentation/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/temp/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/presentation/MeeGo_1_2_Harmattan_Applications_Nokia_Store_Entry_Requirements_v1_1_en/slide-1.pdf /etc/onlinestudios/ /var/onlinestudios/recording/process/presentation/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/temp/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/presentation/MeeGo_1_2_Harmattan_Applications_Nokia_Store_Entry_Requirements_v1_1_en/MeeGo_1_2_Harmattan_Applications_Nokia_Store_Entry_Requirements_v1_1_en.pdf

crashes with "Unrecoverable error: rangecheck in .putdeviceprops"

And this works as expected:
ghostscript -sDEVICE=pdfwrite -dNOPAUSE -dQUIET -dBATCH -dFirstPage=1 -dLastPage=1 -sOutputFile=./presentation/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/temp/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/presentation/MeeGo_1_2_Harmattan_Applications_Nokia_Store_Entry_Requirements_v1_1_en/slide-1.pdf /etc/onlinestudios/ ./presentation/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/temp/0bc06fff1cb99393f3e306002e9e544ff8510040-1349810405174/presentation/MeeGo_1_2_Harmattan_Applications_Nokia_Store_Entry_Requirements_v1_1_en/MeeGo_1_2_Harmattan_Applications_Nokia_Store_Entry_Requirements_v1_1_en.pdf

Note: in second case long paths became shorter and current dir is /var/onlinestudios/recording/process.

My file consists the followinf lines:
/pdfmark {cleartomark} bind def

The problem is actually in processing "-sOutputFile" command line parameter.

File ./base/gsparam2.c contains a define:

#define MAX_PARAM_KEY 255

so if length of path -sOutputFile > MAX_PARAM_KEY security check performed:
char string_key[MAX_PARAM_KEY + 1];

if (sizeof(string_key) < key.size + 1) {
   code = gs_note_error(gs_error_rangecheck);

Seems not a bug, but a strong restriction for input arguments, and "magic" numbers in code.
