Assert Failed: Internal Error - Segmentation Violation

Hi all, I saw a similar request to this last week, but as it involved Powerbuilder, I ignored it :-) As June Tong suggested in her reply, this is being caused by a dodgy char to int conversion (a known bug). I asked the user who caused it initially to tell me what he had been doing, and reproduced it perfectly! The user was running an ACE report from a user-menu that prompts for a 6 digit reference number. The problem is occurring when users mistype the number, and a character gets it by mistake (in this case it was a '-' instead of a '0'). I find it hard to believe that a simple typo can crash the whole online engine. Is there a fix for this. (Yes, I have already told the users to be careful when typing anything in at a prompt!!). We are running Online 7.13. Last weeks problems were reported as being on 7.10 (which we had, and then upgraded when Nils told me it was "buggy"). Here's the output from the log file: 11:07:10 Assert Failed: Internal Error - Segmentation Violation 11:07:10 Who:Session(23, rt10hp@harpm, -1, 170003028) Thread(48, sqlexec, a2001b0, 1) 11:07:10 Results: OnLine must abort 11:07:10 Action: Reinitialize shared memory 11:07:10 See Also: /tmp/af.30184e, shmem.30184e.0 11:07:11 rsinit.c, line 9217, thread 48, proc id 13680, Segmentation Violation. 11:07:11 PANIC: Attempting to bring system down Unfortunately, I don't have /tmp/af.30184e to hand, as our sysadmin decided to reboot the server ;-) TIA, Richard.
