The command in msys2 is executed in terminal app on Windows on ARM platform, sometimes there is no response for a long time.

Commands in msys2 (x86_64) sometimes fail to respond, the process seems to be blocked, but commands in clangarm64 do not.

Could you give a concrete example, preferably a repeatable one? And have you tried running such a reproducer through strace?

[ConanNobita]

For example, when I type the command pacman -Syu, sometimes there is no response. I haven't tried using strace yet, I will give it a try. If msys2 had an arm64 version, it might be even better.

It's not possible to make native AArch64 MSYS2 until Cygwin supports AArch64.

For example, when I type the command pacman -Syu, sometimes there is no response.

This is probably the double-fork issue we've been dealing with for quite some time. I'm not sure which issue/pr best encapsulates the issue:
msys2/msys2-autobuild#62
msys2/MSYS2-packages#4583

Personally, I prefer https://inbox.sourceware.org/cygwin/[email protected]/#t because that UI makes it easier to follow responses (or lack thereof).
