            Bug ID: 22929
           Summary: x86_64 linker seg-faults when creating a shared object
                    from an input containg relocations against a note
                    section

Object file for triggering seg-fault.

The x86_64 linker will generate a seg-fault when asked to create a shared
library from an input file that contains relocations against non-allocatable
sections.  For example try linking the attached object file with:

  ld -shared ifuncmod8.os

The problem in this case is that the input file contains relocations against
a note section.  At a minimum the linker should generate an error message and
exit with a failure code, but a better result would be if the linker could
resolve the relocations instead.
