Can't reproduce this, at least not with a cross gcc (and -m32 -msecure-plt -O2
-fPIC), on neither the original nor the reduced testcase.

Ok, there's a single ppc specific patch in our tree carried over from 4.1.
Maybe it's finally time to investigate why it's still there and if that is
the cause for this problem:
2005-11-28 Jakub Jelinek <jakub@redhat.com>
* config/rs6000/rs6000.c (rs6000_return_addr): If COUNT == 0,
read word RETURN_ADDRESS_OFFSET bytes above arg_pointer_rtx
instead of doing an extran indirection from frame_pointer_rtx.
* gcc.dg/20051128-1.c: New test.

I'm also trying to reproduce it with a plain trunk cross-compiler.

I doubt that could be related. My memory is weak about this stuff and why it
hasn't made it into trunk, search reveals

I can reproduce it on a powerpc machine with
../trunk/configure --target=powerpc64-suse-linux --with-cpu=default32
--enable-languages=c++ --with-long-double-128 --enable-secureplt
--host=powerpc64-suse-linux --build=powerpc64-suse-linux
on rev. 156860. re-trying with current trunk.

It works with rev. 157027. Either it's gone latent or it's fixed.
