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?
