--- Comment #3 from Florian Weimer <fweimer at redhat dot com> ---
I'm afraid this is expected: the dynamic loader from the system libc is not
able to load libc.so.6 from the version you just built. Dynamic loader and
libc.so.6 must come from the exact same build.

You need to run your application with the new dynamic loader, too. Use an
explicit ld.so invocation (see the testrun.sh in the build tree for an
example), or set the loader with the -Wl,--dynamic-linker=3D option. You ma=
y also
have to link to the new glibc startup files,
<https://sourceware.org/glibc/wiki/Testing/Builds#Build100PctNew> has the
details.
