Ruby 3.2 (still in development) started warning about this, see
https://bugs.ruby-lang.org/issues/18007.
Note that the extension docs mention it in
https://ruby-doc.org/core-3.1.1/doc/extension_rdoc.html#label-C+struct+to+Ruby+object:
> The klass argument is the class for the object. The klass should
> derive from `rb_cObject`, and the allocator must be set by calling
> `rb_define_alloc_func` or `rb_undef_alloc_func`.
So in this case we call `rb_undef_alloc_func` to fix the warning.
Verified that this works in robinst/taglib-ruby#115.
Fixes#2257.
The Ruby C API function 'rb_funcall' is used in various places in generated
code for invoking a Ruby method without parameters. The C function uses a
variadic parameter list for the arguments passed to Ruby, therefore in these
cases the list of variadic parameters is empty.
As an optimization Ruby may implement the 'rb_funcall' function as a macro
which however will not accept an empty list of arguments for '...' as of
C99 and C++11.
In order to prevent compiler warnings, this commit replaces all such
occurrences with a call to 'rb_funcall2' (which in its current name
'rb_funcallv' is invoked by the 'rb_funcall' macro anyway, at least for
Ruby 2.6.6).
This bug was introduced in swig-3.0.8 in #146252 adding shared_ptr
support. An ObjectPreviouslyDeleted error was incorrectly thrown
when the pointer was used as a parameter after being set to zero
via a call to 'DATA_PTR(self) = 0'.
It isn't clear to me which approach is better in this corner case,
so I've gone for backwards compatibility and restored the old behaviour.
Closes#602
rb_obj_is_kind_of can no longer be used for type checking as the
smartptr feature type, eg shared_ptr<Derived> cannot be cast to
a smartptr of the base class, eg shared_ptr<Base>.
Previously Derived could be cast to Base as they were in an
inheritance chain and the call to rb_define_class_under() used
SWIGTYPE_p_Base->clientdata for all derived classes.
Now SWIG_TypeCheck is always used.
SF Bug#1292 - Runtime fixes for Proc changes in ruby-1.9 when using STL wrappers that override the default predicate, such as:
%template(Map) std::map<swig::LANGUAGE_OBJ, swig::LANGUAGE_OBJ, swig::BinaryPredicate<> >;
Fixes li_std_functors testcases for Ruby 1.9.
Also rb_respond_to return values have changed subtely in 1.9 and return should be treated as a flag instead of checking for Qtrue, see SF Bug #1159.
Also fix li_std_map, li_std_set silently failing - rb_protect behaviour seems to have changed when an exception is thrown, so code has been changed to use rb_rescue. A call to 'rb_set_errinfo(Qnil)' could have solved this after the rb_protect call, but it is only available in 1.9+ and Ruby API changes are not easily and transparently detectable.
to rubyrun.swg, as they are useful even for not stl stuff.
Added a fragment trait for marking STL containers, but this
fragment cannot be attached due to SWIG %template limitations.

containers that can use one.
Created file rubystdfunctors.swg to allow passing in
Ruby procs as functors to STL functions (swig-user list
suggestion for Python).
Fixed a bug in type_info() always failing for std::set.
Fixed a bug in type_info() always accepting any failed
conversion which could lead to overloaded functions to
fail when input wrong parameters.

Removed object reporting in non-verbose from
newobject demos.
Made wstring treat them as normal strings as
advertised.

Added swig_assert.rb and started using it in some tests.
Added my patches to ruby.cxx, rubyrun.swg, rubystrings.swg
and rubytracking.swg [see: sourceforge]

the methods SWIG_Ruby_ConvertPtrAndOwn and SWIG_Ruby_NewPointerObj,
now tracking information is held on swig_class. This change reduces
significantly reduces the amount of code needed in ruby.cxx, is more robust, and is
more cohesive.
