It actually freezes in the memset() and the problem is the memset.S file in
glibc-2.3.2/sysdeps/powerpc/powerpc32/ which needs to be removed. I knew
this problem existed in older versions of glibc, but I had assumed that it
had been fixed in the newer versions ... I assumed wrong.
When the file is removed everything works fine.
