RE: RE: segmentation fault

Felix- I'm not a Linux guru by any stretch of the imagination, so I'm cross posting this to the more general Informix news list, comp.databases.informix. You will have to look for responses there or subscribe to the informix list (not the same as IDS list) through the iiug. You would probably do well to subscribe in any case, because a fair bit of useful information passes through there. For those who didn't see the original post to IDS list, I'm adding it to the end. As to the current issue, my new best guess is that it may have something to do with the curses or ncurses library, but that's just a wild guess. --EEM > -----Original Message----- > From: FELIX MWANGO MUTALE [mailto:fmutale02@yahoo.com] > Sent: Monday, April 20, 2009 2:57 AM > To: Everett Mills > Subject: Re: RE: segmentation fault [] > > The following e-mail was sent to you via IDS Forum from FELIX MWANGO > MUTALE (fmutale02@yahoo.com) at IP address 196.46.223.3. > > ************************************************************************ ** > ***** > > Re: RE: segmentation fault > > Hello Everett, > > Thanks for your response.
