The following gs command throw a seg fault with some ps documents: gs -sPAPERSIZE=a4 -dFIXMEDIA -dFirstPage=1 -q -dBATCH -dPARANOIDSAFER -dQUIET -dNOPAUSE -sDEVICE=ijs -sIjsServer=hpijs -sDeviceManufacturer=HEWLETT-PACKARD -dDuplex=true -dTumble=false -sIjsParams="Quality:Quality=2,Quality:ColorMode=0,Quality:MediaType=0,Quality:PenSet=0,Quality:FullBleed=0,PS:MediaPosition=7" -sDeviceModel='hp LaserJet_4' -r600 -dIjsUseOutputFD -sOutputFile=- d.ps >d-ijs.pxl Stack trace: £0 0x000000000065ebb7 in clist_icc_writetable () £1 0x000000000065f667 in clist_end_page () £2 0x00000000004d6ac5 in gx_pattern_cache_add_entry () £3 0x00000000004d711c in pattern_paint_finish () £4 0x00000000004e1c46 in interp () £5 0x00000000004e31fb in gs_interpret () £6 0x00000000004d7fc5 in gs_main_run_string_end () £7 0x00000000004d916e in run_string () £8 0x00000000004d98de in runarg () £9 0x00000000004db184 in gs_main_init_with_args () £10 0x0000000000464184 in main () I have tried to find a single page in the documents that triggers this error but failed. The gs versions with this error are: 8.72 9.00 HEAD hplip/ijs version: 3.10.2 OS versions: linux i686 and amd64 with ubuntu 10.4 oder debian lenny Without ijs thre is no error: gs -sPAPERSIZE=a4 -sDEVICE=pxlmono -r600 -dBATCH -dNOPAUSE -sOutputFile=d-gs_pxl.pxl d.ps I have several ps documents with the same error (one is attached).
Created attachment 6760 [details] example ps
Due to other tests i work on, i have tried the above gs command with an extra option (MaxPatternBitmap). Now it works without segfault. The smallest value for this option, used on the attached ps, that works is 26000000.
Henry graciously agreed to take this one. I don't have any particular background for this bug anyway. Also I am not sure why it is P1 other than being a segv.

Has nothing to do with ijs, it is memory corruption handling the icc profiles in the clist patterns and can be reproduced with any device. Start it from the beginning?
