Seems if I recompile a-stunau.o with -O0 -fPIC as opposed to -O2 -fPIC and
relink/reinstall libgnat-3.4.so.1, xnmake works, at least on my x86-64.
When it is compiled with -O2 -fPIC, xnmake dies much earlier under
LD_PRELOAD=libefence.so.0.
>From my debugging so far it looks like if Ada.Strings.Unbounded.Aux.Get_String
compiled with -O2 results in the freed Reference to be still used by subsequent
users instead of the newly allocated one.
