The driver sgirgb is not stable on ia64 architecture as it may crash.
Created attachment 5144 [details] ghostscript-8.57-sgirdb.dif This patch I currently use to fix this problem since ghostscript 8.57
reassign for patch review (I have x64 on peeves)
The submitted patch seems to be against an earlier version of this driver. This issue should have been fixed in revision 9490 (please refer to bug # 690051).
I think sgirgb driver is fixed and the fix is included in v. 8.70. Please re-test the latest version and re-open the bug if something still doesn't work. *** This bug has been marked as a duplicate of 690051 ***
