Ref. https://github.com/espressif/esp-idf/issues/1684 Also, for full RTTI support, libstdc++.a in the toolchain should be built in both with RTTI and w/o RTTI options. Multilib with -fno-rtti flag is used for that. Note that this commit does not actually enable RTTI support. The respective Kconfig option is hidden, and will be made visible when the toolchain is updated.
