Martin Sebor updated STDCXX-198:
--------------------------------

        Summary: [Linux/PPC/64-bit] SIGSEGV catching a rethrown an exception  (was: [Linux/PPC] SIGSEGV catching a rethrown an exception)
    Environment: gcc 3.3.3 -m64 and IBM XLC++ 8.0 -q64 on Linux/PPC  (was: gcc 3.3.3/IBM XLC++ 8.0/Linux/PPC)

The issue seems to be specific to the 64-bit C++ runtime library (that of gcc).
