Below is the backtrace from the Ruby test case you provided.  It shows that it 
fails in SWIG related code.  The attached patch was recently applied in 
version 3.7-3.1 to build with SWIG 4.3 and close the above bug.

The patch is needed to match the latest SWIG so reverting that patch is not an 
option - the code in question can't compile without it.

I think that the root cause of this is SWIG.

Is there anyone who has had previous experience of Ruby and SWIG who can help 
with this?
