Bug was reported to me privately by Pavel Cisar.
When trying to
in python command fails with unresolved _Unwind_GetIP error message.
Client library since 2.1 is statically linked with libstdc++ - this makes it much better usable with other libraries, using another versions of libstdc++. But it must also be linked statically with one more gcc support library, not leaving _Unwind_GetIP unresolved.
