+ * include/ruby/win32.h (FD_SET): change function to macro.
+ To avoid buffer overflow when smaller FD_SETSISE is used in ext
+ libraries.
+
+ * win32/win32.c (rb_w32_fdset): this function is not used anymore.
+ But we leave this for compatibility.
+
+ * win32/win32.c (rb_w32_select_with_thread): fix SEGV when smaller
+ FD_SETSISE is used in ext libraries. Dereference of fd_set pointer
+ causes SEGV.
+
+ * test/-ext-/win32/test_fd_setsize.rb(TestFdSetSize): add tests for
+ above.
+ * ext/-test-/win32/fd_setsize/depend: ditto.
+ * ext/-test-/win32/fd_setsize/extconf.rb: ditto.
+ * ext/-test-/win32/fd_setsize/fd_setsize.c: ditto.

+ [ruby-core:44588] [Bug #6352]
