           Summary: bootstrap-lto creates c-common.s with too many
                    sections on x86_64-apple-darwin10

         Component: lto
        AssignedTo: unassigned@gcc.gnu.org

nlist struct has a one byte n_sect field whichis the index of the section that
symbol is in. Previous to Xcode 4.0, the assembler did not validate that the
n_sect field was not overflowed but now does. This causes the lto-bootstrap on
x86_64-apple-darwin10 to fail with...
