bug report of gtags

[widon]

hello

I use gtags, It's great. But I have a lot of problems when I use it to
fake cscope.
If I set autochdir in vimrc when I use vim.Everything goes wrong. If I
change directory, cs connection will be lost.

Even I do not set autochdir in vimrc if I set grepprg=grep\ -nri\
--include=*.{c,h} and use :grep main . searching in linux kernel source
and :cs f s MD5_DIGEST_SIZE
E262: error reading cscope connection 0
now I must cs kill 0 and cs add GTAGS again....

If I use global I can't change directory and use grep in vim...I fell
really disappoint..
