Waiting for reporter's reply... I think we should automatically close bugs that
are in waiting for more than 2 years.

It no longer reproduce to me.  Hope the problem didn't just get latent again,
but I guess it was fixed as part of numberous fixes to handling COMDATs and
LTO/whole-program privatizing in last few months.

This is very random and I am not sure if this is some memory related issue or
what. Any help will be great.

This is not similar at all. This bug was about a failure to link, if you are
getting an error at run-time then you have successfully linked and it is not
the same issue.

Instead of commenting here please try emailing the gcc-help@gcc.gnu.org mailing
list, including a more complete description of your problem (you didn't say
what's wrong, just showed a stack trace).

Yeah, sounds more like a linker issue.

I am confused why I get link error given that even my *.a exports the
symbol...

libstdc++ does define that function, in string-inst.cc.  And it shouldn't be
defined anywhere else.  I don't know what would be causing that error.
