+Subject: [PATCH] tcltklib.c: use StringValueCStr [ci skip]
+
+* ext/tk/tcltklib.c (set_max_block_time, tcl_protect_core,
+  ip_init, ip_create_slave_core, get_obj_from_str,
+  ip_cancel_eval_core, lib_set_system_encoding,
+  alloc_invoke_arguments, lib_merge_tklist): use StringValueCStr
+  instead of StringValuePtr for values to be passed to Tcl
+  interperter.
