Yes, in every later version.
I chose the first version BTS knew about.

As I read the report there have been numerous fixes after the following
commit:

 https://github.com/Perl/perl5/commit/a5f48505593c7e1ca478de383e24d5cc2541f3ca

       re-implement OPpASSIGN_COMMON mechanism

 This commit almost completely replaces the current mechanism
 for detecting and handing common vars in list assignment, e.g.
 ...

It looks like not all regression are fixed after the re-implementation
and the one
affecting nama is one of them.

I think it should be impossible to trigger an internal assertion in
Perl with pure
Perl code like nama.

Cheers,
Balint
