>Release: FreeBSD 2.2.5-STABLE i386
>Environment:
A 2.2-STABLE system (as of 11.25.97), with old user-compiled binaries
from the 2.1-STABLE branch.
>Description:
A new function (issetugid()) is called from the latest
libtermcap, but the version number wasn't bumped up so old binaries
fail. The old programs are linked against libc.so.2.2 and
libtermcap.so.2.1: libc.so.2.2 lives in /usr/lib/compat, but
libtermcap.so.2.1 lives in /usr/lib. =( So the last time libtermcap
was updated and installed, the old binaries pulled it in and died.
tgetent() was trying to call issetugid(), which libc.so.2.2 dosen't
have.
>How-To-Repeat:
Run the `resize' program from a 2.1 version of XFree86 (or any other
program that uses termcap from 2.1) on a current 2.2-STABLE system (after
1997/11/21, when revision 1.7.2.1 of termcap.c was committed).
ldd resize
resize:
-lgnumalloc.2 => /usr/lib/compat/libgnumalloc.so.2.0 (0x2001f000)
-ltermcap.2 => /usr/lib/libtermcap.so.2.1 (0x20021000)
-lc.2 => /usr/lib/compat/libc.so.2.2 (0x20025000)
>Fix:
Bump up the minor version number for libtermcap (like what was
done in current), and add the old libtermcap into /usr/lib/compat.
