[Bug c++/34853] New: c++ runtime of basic_string has a bug in certain case

[myan at microstrategy dot com]

The following change in basic_string.tcc is not valid in my usage. A java
application loads c++ jni shared library that is compiled with
-D_GLIBCXX_FULLY_DYNAMIC_STRING. Please see attached test files.

------- Comment #6 from pcarlini at suse dot de  2008-01-19 20:24 -------
This is not a bug, and already spuriously reported: yu *cannot* use
-D_GLIBCXX_FULLY_DYNAMIC_STRING, it's completely unsupported and not described
anywhere in the documentation. You can only completely rebuild the library with
--enable-fully-dynamic-string.
