  Hi, yeah, I've tracked this one down to several things:

1.  The new debug_pubtypes section needs to be linked in.  The cygwin linker
scripts were patched at

    http://sourceware.org/ml/binutils-cvs/2009-06/msg00203.html

2.  There's a bug in BFD that doesn't understand the new form of the .loc
directive that specifies a discriminator.  See

    http://sourceware.org/ml/binutils/2009-06/msg00481.html

3.  There may or may not be a problem in a recent patch to bfd/coffcode.h that
attempted to fix some of these problems.

4.  All of this may or may not have been conflated for a while with the recent
SRA bug that caused binutils to be miscompiled.

  I *think* that's all of it.


    cheers,
