> Speaking of parallelism: When I tried to find where the memory losses come from, I saw a lot of global variables like `link_command_spec' in `gcc.c'. Does it mean that compiling the context is not thread-safe? (I may have missed that in libgccjit's documentation.)

It is thread safe because in practice the compilation itself it's all
guarded by a mutex, see [1] for more details.

That's another good reason (I forgot to mention) why sub-processes are a
good option for Emacs (we run many compilations in parallel).
