It does correctly report a failed exit code. The lack of message is
because git assumes that the helper will produce a useful message before
dying, but obviously it doesn't.  There's already a patch[1] to fix this,
but it hasn't been merged yet.

As for why dmesg reports git-remote-http, I'm not sure. If you "strace
-f" the command, you can see that git is running git-remote-https. Why
the kernel chooses to report "git-remote-http", I don't know; you'd have
to look into how the kernel makes that decision. But I doubt it is
related to the reason for the segfault in the first place.
