I'm looking at your patch now; assuming I don't find any problems with it, I
will try to get it committed.

Has anyone actually committed this fix?  I'm not seeing it in my tree yet

Could you be a little more specific please?  What header are you seeing where?

Even though I logged in to Bugzilla, I can't seem to edit any of the fields
above, but to the best of my knowledge a patch to fix this problem has been
committed to GCC and this bug should be marked as fixed and closed.

When the preinit flag is used, the vtable verification constructor
initialization function was getting written to the assembly file before
cgraph_process_new_functions was being called (to process the new function),
which was causing an assertion failure in decide_is_symbol_needed (which
expects the symbol NOT to have its decl assembler name yet).  The fix is very
simple...reorder those two events.  This should not cause any errors.  I have a
patch that does this, which I have tested both on this test case and with the
new libvtv testsuite, and it passes in both places:

I will submit this patch for review soon.

Reorder two function calls to prevent an ICE.
