Dear R Team,

Today I upgraded from R 2.2.2 to 2.8.1  ...then I restarted, did a bunch of
work, and tried to quit.  (Note that I have oodles of stuff saved in the work
environment; took almost a full minute to start up.)  After over 10 minutes, it
was still trying to close up, and the problem (below) for DBfetch was mentioned,
plus it said

*** caught segfault ***  
address 0x7fffdeb1  
cause 'memory not mapped'  

(retyped from my notes, no way to grab)

After about five more minutes, I did a Force Quit.  Then I reproduced the bug. 
I opened R, loaded a CSV file from my previous day's work, then quit - here's
what happened:

> quit(save="yes")
Error in .Call("R_lazyLoadDBfetch", key, file, compressed, hook, PACKAGE =
"base") : 
  C symbol name "R_lazyLoadDBfetch" not in DLL for package "base"
> quit(save="no")

(that latter command worked, 2nd time, no need for Force Quit)

Yarg!  I know I can work around this using write.csv(), but I guess my lesson is
never to change versions in the middle of one's dissertation analyses!

with thanks,

Anne G.
