vi or vim doesn't start after Cygwin update

Question

OS: Windows 10 Pro

Cygwin Setup: 2.889 (64 bit)

vim: 8.0.1567-1

terminal: mintty 2.8.4

cygwin: 2.10.0-1

I updated cygwin packages on 2018/03/09 and needed to restart OS to complete update. But some services were running so I didn't reboot at that time. In next day I rebooted my windows but found vi/vim command didn't response any more. Even I tried to enter vi, vim or vi -V, vim -v, vim text.txt the terminal only response nothing.

$ vi

$

I checked vi and vim still exist.

$ ls -l `which vi vim`
-rwxr-xr-x 1 bobchang None 1014803 三月  5 13:30 /usr/bin/vi
-rwxr-xr-x 1 bobchang None 2645011 三月  5 13:30 /usr/bin/vim

I checked setup.log vim was erased and installed.

I manually removed and installed vim with related package but helpless.

Do anyone know how to solve this issue or how to debug to find the solution?

Answer 1

__memcpy_chk belongs to cygwin1.dll

It was added on the last release
https://www.cygwin.com/ml/cygwin-announce/2018-02/msg00002.html

Reinstall the cygwin package as it seems was not correctly upgraded.
