I did a system update yesterday (pacman -Syu --force because of /etc/skel/.vimrc), then msys got crashed:
+ double click on mingw64_shell.bat, MinTTY complained could not load icon from '/msys2.ico';
+ close this messagebox, in the mintty window, it shows /bin/bash: No such file or directory;
+ try running bash --login in the bin folder, I got 0 [main] bash 3428 cygwin_exception::open_stackdumpfile: Dumping stack trace to bash.exe.stackdump;
+ I've tried sh, python et.al., some of them ended with such a stack dump;
+ and the dumped file is, for example, like this:

Because I can't make the shell ready, pacman can not run correctly, thus I don't know how to upgrade or downgrade all those packages, to make msys2 at lease the same before I did the update.

My environment is windows 8.1 x64, codepage 936. This issue exists in another PC with windows server 2012 R2, codepage 936. The system is up-to-date.

BTW, I've found that in dash, the root it reports is not the msys2 folder, but its parent folder. (i.e., for example, I've unpack the basic system to C:\msys2, thus dash is here: C:\msys2\bin\dash.exe, and in this dash, / is actually C:\ but not C:\msys2).
