[MUD-Dev] Technical programming question (circular buffers & logging)

Well, through no fault of my own *grin* a nasty bug has entered
my code! It seems to be a memory corruption bug, as all good ones
So, I turned on my verbose logging and after about 10 minutes I have a 15MB file.
(The trouble spot is called *very* often.)
So, what I want to do is modify my logging class (basically just
an ofstream with some flags tacked on it). I was thinking about
making it a sort of ring-buffer where it just kept the last 50k
or some other nice round number.
This would be nice because I could turn logging on a really
verbose level, and not fill up my HD. Usually I only want
the last little bit of the log anyway.
I think I could write my own thing to do this, but I was wondering
if anyone knew of any tricks with files, or ready-built libraries
to do something like this...
Oh, one final thing: If I keep it all in memory, I will want to
(at least) catch the SIGSEGV can flush it to disk at that time.
Does anyone forsee any problems with this??
Thanks a heap,
