Is there anything else involved? I’m only doing:

    Emacs -Q

    M-: (make-temp-name "index.magit.") RET

Can you try either running in a debugger and finding out what the
‘data’ variable contains at line 716 of fileio.c (just before
‘if (!check_existing (data))’), or putting something like:

    printf("filename: %s\n", data);

on that same line?

The make_temp_name function generates a name and then tests to see if
it already exists and it’s this test that’s throwing up the error. My
first thought is that it’s possible that it’s generating an invalid
file name, so it would be good to see exactly what that name is.

Also, what’s the PWD?

Thanks!
