Wow, nice catch.  This bug has been there since imported CUs were
implemented.

I mildly don't like putting this here.  Ideally it would be handled
purely in the DWARF reader.  However, I see this as a side effect of the
way that psymtabs are currently managed ("poorly").  I have some patches
that change this, and I suppose this could be modified on that branch.

Meanwhile, this patch is ok.  Thank you for find this and for this fix.

Tom
