Re: RCS log gets up to large numbers of revisions then RCS will core dump

[Paul Eggert]

Thanks for the bug report and test case. Although RCS 5.7 is two decades 
old and RCS has mutated quite a bit since then, there is a similar 
problem with the current code. I installed the attached patch to fix the 
problem for your test case. Some unbounded recursion still remains 
(marked with FIXME comments), though it should be less likely on 
real-world data.
