> @erik.pilkington Is it acceptable/good practice to pass `(nullptr, 0)` here? At the moment this safes some lines of initialization checks for `m_IPD_buf` and `m_IPD_size`.
Sure, thats fine! Those parameters act the same way as `buf` and `size` in __cxa_demangle.

`getFunctionBaseName` will return nullptr if the mangled name isn't a function. Is it a precondition of this function that m_IPD stores a function? If not, it looks like you'll leak the buffer.
