It is reproducible only if Emacs runs under gmalloc trace utils. Do
you need that?

Additionally I can see that if there is any package like
persistent-scratch, Emacs cannot be killed with C-x C-c as package
asked to be saved. There is no way to exit Emacs is disk space is full
and some package want to save data on exit.
