Bug#374994: cscope crashes while being driven by vim

["J. Bruce Fields" <bfields@fieldses.org>]

This looks like the same bug as #132466; if I start up vim and do a ps,
I see:

 5019 pts/2    S+     0:00 view fs/nfsd/nfs4acl.c
 5022 pts/2    S+     0:00 cscope -dl -f cscope.out

strace'ing while I change vim's window size shows:

Process 5022 attached - interrupt to quit
read(0, 0xb7f4a000, 4096)               = ? ERESTARTSYS (To be
restarted)
--- SIGWINCH (Window changed) @ 0 (0) ---
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
Process 5022 detached

and subsequent attempts to use cscope from within vim get "error reading
cscope connection 0" until I restart cscope (with ":cscope reset"), at
which point it will last until the next time I resize the window.
