MINGW-packages: libssp-0.dll broken in mingw-w64-x86_64-gcc-libs-12.2.0-5 package

Description

After updating to mingw-w64-x86_64-gcc-libs-12.2.0-5, I get the following error when running git --version:

*** stack smashing detected ***: terminated

Using git from the package git-for-windows/mingw-w64-x86_64-git 2.38.1.1.b85c8f604d-1.

Switching to libssp-0.dll from the previous package appears to work fine.

Verification

I have verified that my MSYS2 is up-to-date before submitting the report (see https://www.msys2.org/docs/updating/)

Windows Version

Microsoft Windows [Version 10.0.19044.2130]

MINGW environments affected

MINGW64
MINGW32
UCRT64
CLANG64
CLANG32
CLANGARM64

Expected behavior

git to run without terminating.

Actual behavior

git terminates with the error: *** stack smashing detected ***: terminated.

Repro steps

Run git --version with git from the package git-for-windows/mingw-w64-x86_64-git 2.38.1.1.b85c8f604d-1.

Most upvoted comments

comments like the above do somewhat concern me because it doesn’t really help to encourage people to contribute towards these projects.

@nga888 @revelator you have no idea how discouraging your comments are. It really makes me feel very much devalued. Like, you are fine to dump all the work on me, but when I point out that I feel totally taken advantage of, you’re saying that I do something wrong? Not cool.

Yes, I have seen this, and fixed it in Git for Windows.

About this report: I do not appreciate how blatantly some people disregard the stern warning at the top of https://github.com/git-for-windows/git/wiki/Install-inside-MSYS2-proper.

Anybody is free to do as they wish, but if they use an unsupported setup, they have no right to burden anybody else with fixing their problems with said setup. That’s a self-inflicted problem and it is outright unfair to expect others to help solve it.
