12.4.10.3 Considerations for non-C code

The blob API assumes that Prolog will take care of memory management, using the release(c)allback to handle any cleanup.

Other programming languages have their own memory management, which might not fit nicely with the Prolog memory management. For more details on blobs written with C++, see C++ interface to SWI-Prolog (Version 2).
