There are 86 object files in the src directory, but ralloc.o is 
not amongst them.

I don't mind building Emacs in other ways, as long as it's 
reasonably straightforward.  Unfortunately providing an 'emacs -Q' 
way to reproduce the bug could be tough, since I can only trigger 
it in Gnus so far, so this may depend heavily on my Emacs config.
