Comment 1 Pierre-YvesChibon 2011-08-10 13:14:42 UTC
Could you provide some information on how to reproduce this bug ?

Comment 2 Thomas E. Dickey 2011-08-10 22:41:59 UTC
Possibly related, I had a patch from Miroslav Lichvar which I added
in 20100123 (no bugzilla number) which addressed this symbol in
conjunction with the normal/wide libtinfo's.

Comment 3 Pierre-YvesChibon 2011-08-11 05:20:26 UTC
I am a little bit confused about your comment Thomas. Could you give a bit more info/context ?

Comment 4 Thomas E. Dickey 2011-08-11 08:39:47 UTC
I added _nc_screen_of in 20080531 (between 5.6 and 5.7) as part of some
changes to allow improved reentrancy.  That happens to be associated
with the lower-level terminfo functions.  At some point (I don't recall)
Red Hat started packaging ncurses using the --with-termlib option, which
provides the low-level terminfo functions as a separate library (typically
referred to as libtinfo).

An application can have problems loading libtinfo automatically as part
of loading libncurses / libncursesw for several reasons.  One (the fix
mentioned in Comment #2) was that the binary compatibility between the
copies of libtinfo built as part of building libncurses differed from
the libncursesw.  However, Red Hat was delivering one copy of libtinfo
to satisfy dependencies from both libraries.

My comment was suggesting that perhaps some similar issue had crept
in, and that it might require getting more information.

(My own builds use libtinfo in some platforms, but usually use rpath
so that I can install/use these separately from whatever the different
distributors provide as system libraries - so I'm testing it in a
different configuration, and can overlook things).

Comment 5 Pierre-YvesChibon 2011-08-11 09:57:59 UTC
So the problem is from ncurses.

I am reassigning the bug to the ncurses component.

Thanks for the information.

Comment 6 Miroslav Lichvar 2011-08-12 15:17:12 UTC
This is odd. The symbol is in libtinfo.so.5. If it wasn't all ncurses applications would probably fail. The "import vte" command also works here.

Comment 7 Thomas E. Dickey 2011-08-12 19:18:39 UTC
I'm puzzled, too.  I don't see any likely conflicting library
paths in the log (such as /usr/local/lib).  I guess starting
by asking the reporter if it can still be reproduced is where
to start.

Comment 8 Fedora End Of Life 2012-08-07 17:25:29 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
