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?
