All tests pass on OSX Lion 10.7.3 using XCode-4.3.2 when I build
the software with clang or llvm-gcc with one major caveat.  I had
to runtest with gcc-4.6.

It passes all when I build with clang-3.1.318 and test with gcc-4.6.
It passes all when I build with llvm-gcc-4.2.1 (llvm 2336.9) and
test with gcc-4.6.

It still fails if I runtest with clang or llvm-gcc.  So why does that happen?
If it can build all the libraries at -Os using only those compilers,
why can't the tests pass using those compilers?  Why am I forced
to install gcc-4.6?  OSX doesn't come with gcc anymore, and building
that to make your testsuite work was not fun.  But I did it because
I'm not going leave this as a mess on my part.   OSX uses
DYLD_LIBRARY_PATH, not LD_LIBRARY_PATH, but as I mentioned
I am not a programmer.  So I have no idea what to look for.  In a
previous message you said my compilers have optimization problems.
If that was the case, why did the test at -O0 fail?  I'm sure you'll
just ignore this anyway, but I did my part.
