Thanks for the nice test case.  It made my job a lot easier. :-)

The bug is in the dynamic linker.  I'll append the patch to the end of
this mail.  The patch is relative to -stable, but the rtld.c source is
identical in -current.

I'm doing a little more testing, then I'll commit the fix to -current.
And I'll ask Mr. Release Engineer to let me merge it into -stable.
