Here, I've got:

00000000      D  *UND*  00000000 exception virtual table
0004a678 g    DO .data  00000018 exception virtual table
00040e58 g    DO .rodata        00000010 logic_error virtual table
00040e18 g    DO .rodata        00000010 out_of_range virtual table
00039bc8 g    DF .text  00000014 __eh_alloc

It seems weird to have "exception virtual table" showing up as being
both defined and undefined.

I can redo the link - and I get the same thing:

0004a748 g    DO .data  00000018 bad_exception virtual table

I'm using binutils 2.9.1.0.19a.

I tried downgrading to binutils 2.9.1.0.15 (from Corel), and I get the
exact same results.
