NetworkManager failed to load correctly with FORTIFY_SOURCE=3. Reverting to FORTIFY_SOURCE=2 fixed the issue. Reproducible: Always
Can you give us a backtrace and/or error output? FWIW, tamiko seems to have hit this too, and apparently is fixed in 1.38.
Yeah, let me break it again. 😜
(In reply to Randall from comment #2) > Yeah, let me break it again. 😜 fwiw it's not a *huge* deal if you don't want to bust your internet again, b/c we know 1.38 is somehow okay, but I'm curious :)

That was supposed to be strace. Lol.

We'll want coredumpctl output from when it crashes too. You'll need debugging symbols on networkmanager, glibc, and probably glib to make it useful.
From the backtrace shared with me, I think this was either fixed in: - https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/7b3466fc4cfedd85992fa24953a08f9f07d6d28f (or similar) or - parse_env_file (and related functions) => https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/c44b49db6f3deb6a42bbd617b4b672076959638c => https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/1188 => https://bugzilla.redhat.com/show_bug.cgi?id=2073067 So it's seemingly fixed in 1.38.0. bt: ``` #0
