Hi Eli,

This is what I get (obviously odd-looking string):

(gdb) frame 9
#9  0x0000000000624397 in Fread_from_string (string=54138084, start=0,
end=0) at lread.c:2075
2075      ret = read_internal_start (string, start, end);
(gdb) p string
$15 = 54138084
(gdb) xstring
$16 = (struct Lisp_String *) 0x33a14e0
"(nilory is relative, it is com"

Looks like the 'nil' argument in '(string-match-p "." nil)' somehow did
this?

(BTW this debug session is on the 2f67f8a commit of master (very recent,
today). But the bug is present on emacs-25 too.)
