<pre>Both clang and gcc have problems with these tests.
In the first one, if it is compiled as
$CXX -c test1a.cpp -fPIC -O2
$CXX -c test1b.cpp -fPIC
$CXX test1b.o test1a.o -o t1
the resulting program will segfault trying to write to constant memory.
On the second test, if compiled as
$CXX -c test2a.cpp -fPIC -O2
$CXX -c test2b.cpp -fPIC
$CXX test2a.o test2b.o -o t2
it will return the wrong value since the linker will keep the zero initialized
x but the inlined f will think that x is constant and doesn't need
initialization.</pre>
