Hi all, I have found the cause of this problem. It due to some code in a library I loaded into Fs, it set SIGPIPE handler, the handler seemed to be invalid when SIGPIPE is fired, so FS is broken.
address, so,

Hi all and merry holiday, I have encounter fs core dump many times when I exit fs_cli, I'm using the fs 1.0.5pre9.
I can reproduce this fault by follow steps
1.launch fs with console
2.press ctrl+z to ext from fs console
3.run fs_cli (from local)
4.press ctrl+z to exit fs_cli (or type /bye)
5.fs core dump.
This fault is not reproduced every times, but quite frequent. does some have encountered the same problem or have any idea about it?
Any suggestion is appreciated!
