This may be related to debug/17406.  Try the patches here:
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17406>.

Note that Dwarf-2 debugging does not work properly on 3.4 for Windows
targets, and probably never will on this branch.  It would be helpful to
see if you could recreate it on a recent 4.0 snapshot.

Make sure to include all of the usual info in your bug report, such as
the configure options GCC was built with.  Since it seems like you're
using the --with-dwarf2 option, you should know that it will only give
favorable results if you are using a very recent binutils snapshot.  (I
don't think the ones on mingw.org are new enough.)

Keep in mind that pretty much anything with GCC on Windows outside of
the official MinGW and Cygwin releases is pretty bleeding edge; expect
to do a lot of bleeding.
