[Bug other/39573] linking fails when optimizations are enabled

["fpbeekhof at gmail dot com" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #1 from fpbeekhof at gmail dot com  2009-04-03 12:01 -------
I've tried compiling the same code on several machines. Outcome: intel machines
are fine, AMD machines exhibit this behaviour.

The second AMD machine has ubuntu 8.04 on it, and a different compiler version:
$ gcc -v
Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2
--enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr
--enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu
--target=x86_64-linux-gnu
Thread model: posix
gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)

Still, the result is the same:
$ make CNF=gcc
scons -j 2 CNF=gcc MODE= BACKEND= CVMLCPP_PREFIX=/user/l1/beekhof/

I'll see if I can make a reduced test-case...
