           Summary: libsupc++ does not export __cxa_get_globals or related
                    functions
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: coppro@users.sf.net


Some functions, including __cxa_get_globals, are not exported properly by
libsupc++. This is contrary to the ABI, which requires these to be in cxxabi.h,
and makes it impossible to implement std::uncaught_exception() properly in a
different standard library on top of libsupc++. These functions are in
unwind-cxx.h, which are not in the public interface of the library.
