I think I had the same problem on my machine: clang-3.2 had been
working for months, then I upgraded to g++-4.8 from experimental when
it was officially released (which pulled in some other libc stuff),
and then I got the "error in backend":
fatal error: error in backend: Cannot select: 0x49635c0: i64 = fabs

In function:
_ZN7testing8UnitTest17AddTestPartResultENS_14TestPartResult4TypeEPKciRKNS_8internal6StringES8_
make: *** [test/gtest.o] Error 1
However, when I upgraded to clang...exp9, I could not reproduce this
problem anymore, nor was there a problem with the original ladmin.cpp
example.
Thanks,
Ben
