--- Begin Message ---Package: mg Version: 20110905-1 Severity: normal If I open a file starting with ~, not specifying the username, mg uses getlogin to try to figure who I am. On my machine, getlogin is returning NULL and mg doesn't test for this. I'm uncertain as to why getlogin is returning NULL -- because I have no utmp or wtmp? Or because /proc/self/loginuid returns UINT32_MAX ? -- but it's a permitted error signalling value. Specifically, in fileio.c:adjustname, /* first handle tilde expansion */ if (fn[0] == '~') { [...] if (ulen == 0) /* ~/ or ~ */ (void)strlcpy(user, getlogin(), sizeof(user)); And then strlcpy dereferences the NULL pointer it was passed. I'm not certain what the right solution is if we can't get the user's name, but segfaulting is definitely right out.
