One note about this, in reading the bug report for pr/2939 I'm unsure
that the discussed scenario actually matches my test case, but you
guys are the experts. To be clear though, I have not explicitly used
the --as-needed flags in my repro case.  In the example H.J. gives in
the bug, the symbol in the "missing from main hash" error message is
still a valid string, so it doesn't fully iilustrate that the pointer
is in fact dangling and in many cases will be a garbage string.

Anyway...just wanted to make sure we're really talking about the same thing. :-)

Thanks all...
