           Summary: [4.9 Rgression] lto1: internal compiler error: in
                    add_AT_specification, at dwarf2out.c:4096

           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal

At r207473 compiling gfortran.dg/namelist_51.f90 with '-g -flto' gives the
following ICE

lto1: internal compiler error: in add_AT_specification, at dwarf2out.c:4096

Compiling the tests with '-g' or '-g -flto -O3' gives on x86_64-apple-darwin13
the warning

warning: invalid DWARF generated by the compiler: DIE 0x000001f0 has multiple 
AT_calling_convention attributes in
'/var/folders/8q/sh_swgz96r7f5vnn08f7fxr00000gn/T//ccLHCwpM.ltrans0.ltrans.o'.

Note that before r207471 (and after r205679) the ICE was

/opt/gcc/work/gcc/testsuite/gfortran.dg/namelist_51.f90: In function
