library/type_name.hpp line 30: the header provides typeid demangle, however for compilers using cxxabi (eg.: GCC), it calls abi::__cxa_demangle with a buffer allocated on the stack.

    char buf[1024]; // <-- error is this
    size_t size=sizeof(buf);
    int status;
    char* res = abi::__cxa_demangle (name, buf, &size, &status);

Relevant quotes from the cxxabi documentation:

output_buffer A region of memory, allocated with malloc, of *length bytes, into which the demangled name is stored.

The caller is responsible for deallocating this memory using free.
