Dwarf2 Dies on "throw()"

[Jeffrey Oldham]

cc1plus compiled for mips-sgi-irix6.5 with -g Dwarf2 debugging dies
with an internal segmentation fault in
gcc/dwarf2out.c:dwarf2out_decl(0x0) given the following code:

    void
    foo () throw ()
    {
      return;
    }

It also seems to die if the "throw" function specification has a type.

What code changed today (26Feb) to cause this change?  gcc/dwarf2out.c
did not change.

Thanks,
Jeffrey D. Oldham
