This is a duplicate of pr48086. If you want to use lto on darwin, you have to revert to Xcode 3.2.5 or try the patch in http://gcc.gnu.org/ml/gcc-testresults/2011-03/msg01695.html (see pr48108). *** This bug has been marked as a duplicate of bug 48086 ***
If you want to keep most of Xcode 3.2.6, but live dangerously with lto, you can also do what I have done: i.e., replace Apple Inc version cctools-795~45, GNU assembler version 1.38 of 3.2.6 with Apple Inc version cctools-782~33, GNU assembler version 1.38 from 3.2.5. The relevant beasts are in /usr/libexec/gcc/darwin/x86_64 and /usr/libexec/gcc/darwin/i386/. Use at your own risk!-)
