Travis Vitek commented on STDCXX-602:
-------------------------------------
Ah, you beat me to it. I was waiting for the commit to show up in the mail
archives so I could reply with this same question there. Yes, the method
_C_grow() is exported from the shared library, so this is likely a binary
compatibility issue.
Unless someone indicates otherwise, I'm going to leave the fix on trunk and
then set the fix version of this issue to 4.3.

> ...the function is inline and only called from std::stringbuf::str().
> Removing it (by virtue of expanding its body into str()) will reduce the
> number of symbols "exported" from the library and decrease the risk of
> breaking binary compatibility (see STDCXX-142 and the discussion thread at
> http://www.nabble.com/difference-in-exported-symbols-between-4.1.3-and-4.2.0-15d-dll%27s-%28MSVC-7.1%29-tf4641636.html)
