in thread panic: regfree data code 'ð' during global destruction. error when joining threads

thanks for the common sense advice. I took my working Thread module and instead of slamming it into my other system, added elements until the break was detected several hours later. I don't know exactly the cause, but it is a combination of using: 
use Data::Dumper;
$Data::Dumper::Deparse=1;

along with a number of objects for the thread->join to clean up and the twist, a subroutine with a regular expression in it, hence the regfree reference.

Thanks everyone for their help.

    Yep! That'd do it. From the docs for D::D:

    Caution : use this option only if you know that your coderefs will be properly reconstructed by B::Deparse.

    I seriously doubt if that option or B::Deparse have ever been tested seriously in a threaded environment.

    If you can see your way clear to producing a small tst case demonstrating the panic, and raising a perlbug, it might be get fixed sometime.
