We do not actually custom-build grep, we use the grep package from the MSYS2 project. Maybe report it there (i.e. at https://github.com/msys2/MSYS2-packages/issues/new)?

[dscho]

Oh, I think I know what it is. MSYS2's executables are not meant to be called from CMD, they are meant to be called from MSYS2's Bash, more specifically: after /etc/profile had a chance to run.

So it is no wonder that in your use case, LC_ALL is not set, and it would appear that this triggers a code path that crashes.

You can easily fix this on your side by calling set LC_ALL=C.UTF-8 first.

Since

1. you have a work-around,
2. you now know which bug tracker would be more appropriate for this bug, and
3. you don't answer me,

I will close this ticket.

[NTMan]

you have a work-around,

Unfortunately work-around not worked. Yes, it solves the issue with crashes but for now grep.exe hangs when I apply set LC_ALL=C.UTF-8 to CMD or launch from bash.

In this window with grep.exe running, nothing has been happening for a day.

The previous version didn't have this issue.

Anyway thanks for respond.
