Hi Dmitry,

Thanks for the new version, but it looks like we still have some issues:

| Mangler.cpp:(.text._ZN4SPIR13MangleVisitor18recordSubstitutionERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE[_ZN4SPIR13MangleVisitor18recordSubstitutionERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE]+0x23f): undefined reference to `std::__throw_bad_array_new_length()'

Can you have a look at this please?
