This does seem to ring a bell:

  http://gcc.gnu.org/ml/gcc/2002-11/msg00149.html

I do not have ready access to a DW-2 MinGW build though, so
I can't verify if it still is valid.  (It does not fail with
current mainline on i686-pc-linux-gnu.)

Danny, is it possible for you to see if this testcase still
fails?

Ranjit.
