Well, ldd shows that smbtree depends on popt and glibc. According to gdb,
the problem seems to be in glibc (/usr/lib64/gconv/IBM852.so belongs to
glibc):
$ gdb smbtree

(gdb) r

So I decide to downgrade glibc first, but it did not help. Then I downgrade
linux-headers and re-emerge (downgraded) glibc and samba (for sure). Again
without success. :-( I removed -ftracer at first of course.
I'm stuck now. I don't believe that rebuild of whole system (without
-ftracer) fixes the problem because /usr/lib64/gconv/IBM852.so depends only
on libraries from glibc.
$ ldd /usr/lib64/gconv/IBM852.so
libc.so.6 => /lib/libc.so.6 (0x00002aaaaabce000)
/lib64/ld-linux-x86-64.so.2 (0x0000555555554000)
$ ldd /lib/libc.so.6
/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
$ ldd /lib64/ld-linux-x86-64.so.2
statically linked
What do you think?

Maybe something in your toolchain is broken. If you don't have a trusted
toolchain then you can borrow the toolchain from a livecd to rebuild gcc,
binutils, and libtool.
