Thanks. I got that far too, and I also bisected the 'Modification of a
read-only value' thing to ce0d59fdd1c7d145efdf6bf8da56a259fed483e4
but that doesn't help much.

I note this is already reported upstream as
 https://rt.perl.org/Public/Bug/Display.html?id=120170
(unfortunately with no action since 2013), and very recently also
against the 'threads' distribution at
 https://rt.cpan.org/Public/Bug/Display.html?id=102406
