atexit() segfault in 2.2.3 and more

[Andreas Steinmetz]

Hi,
when building static (-static) versions of fileutils-4.1 with gcc 2.95.3 the
resulting binaries segfault in atexit(). Temporary fix for me is an atexit()
shim diverting the call to on_exit().

After the upgrade from 2.2.2 to 2.2.3 the following packages stopped working
and had to be rebuilt against the new library:

ypserv-1.3.12
nfs-utils-0.3.1 (rpc.kstatd)

Installing glibc-2.2.3 did cause problems too:

[snip]

make  -C linuxthreads subdir_install
make[2]: Entering directory `/usr/src/glibc-2.2.3/linuxthreads'
/bin/install -c -m 644 ../linuxthreads/sysdeps/pthread/pthread.h
/usr/include/pt/bin/install -c -m 644 semaphore.h /usr/include/semaphore.h
/bin/install -c /usr/src/glibc-2.2.3/build/linuxthreads/libpthread.so
/lib/libpthread-0.9.so.new
mv -f /lib/libpthread-0.9.so.new /lib/libpthread-0.9.so
echo libpthread-0.9.so /lib/libpthread.so.0 >>
/usr/src/glibc-2.2.3/build/elf/symlink.list
rm -f /usr/lib/libpthread.so.new
/bin/sh ../scripts/rellns-sh /lib/libpthread.so.0 /usr/lib/libpthread.so.new
mv -f /usr/lib/libpthread.so.new /usr/lib/libpthread.so
/bin/install -c -m 644 /usr/src/glibc-2.2.3/build/linuxthreads/libpthread.a
/usr/lib/libpthread.a
: /usr/lib/libpthread.a
make[2]: Leaving directory `/usr/src/glibc-2.2.3/linuxthreads'
make  -C resolv subdir_install
make: /lib/libc.so.6: version `GLIBC_2.2.3' not found (required by
/lib/libpthread.so.0)
make[1]: *** [resolv/subdir_install] Error 1
make[1]: Leaving directory `/usr/src/glibc-2.2.3'
make: *** [install] Error 2

This happens as (at least my) make (make-3.79.1) is linked against
libpthread.so.0 which is installed before the symbolic link /lib/libc.so.6 is
set up to point to the new glibc. Workaround is to use a statically linked make
during installation (if you have one available).

The patch http://sources.redhat.com/ml/bug-glibc/2001-05/msg00080.html is
definitely required, too.

Oh, I forgot:
