This is actually the same bug as 23949, the problem is that
string-match-p let-binds inhibit-changing-match-data and causes problems
for the debugger code.
(http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23949#56)
In version 24.5, emacs -Q then evaluate (string-match-p "." nil) gives
"button-at: Args out of range: 0". In version 25.0.95 it gives
"find-auto-coding: Wrong type argument: stringp, nil"; presumably the
specifics of the code the debugger runs changed somewhat.
