+ error: Print 32- and 64-bit integers portably (Bug#8435).
+ Without this change, on typical 64-bit hosts error ("...%d...", N)
+ was used to print both 32- and 64-bit integers N, which relied on
+ undefined behavior.
+ * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
+ New macro.
+ * lisp.h (error, verror): Mark as printf-like functions.
+ * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
+ Report overflow in size calculations when allocating printf buffer.
+ Do not truncate output string at its first null byte.
+ * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
+ Truncate the output at a character boundary, since vsnprintf does not
+ do that.
+ * charset.c (check_iso_charset_parameter): Convert internal
+ character to string before calling 'error', since %c now has the
+ printf meaning.
+ * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
+ overflow when computing char to be passed to 'error'. Do not
+ pass Lisp_Object to 'error'; pass the integer instead.
+ * nsfns.m (Fns_do_applescript): Use int, not long, since it's
+ formatted with plain %d.
+
* eval.c (internal_lisp_condition_case): Don't pass spurious arg.
* keyboard.c (access_keymap_keyremap): Print func name, not garbage.
