This looks like a problem in perl itself possibly causing random crashes
elsewhere, too.

Reproduction with the perl-debug package shows the internal assertion:

sudo apt-get install perl-debug
sudo apt-get build-dep nama
apt source nama
cd nama-*
dpkg-buildpackage
...
ok 57 - set JACK client as input
sax: JACK source port is sax_in. Make connections manually.

Track sax: source set to JACK manual port sax_in
Failed 69/126 subtests
t/13_io.t .......
1..1
ok 1 - use Audio::Nama::IO;
ok
..

PERL_DL_NONLAZY=1 PERL_USE_UNSAFE_INC=1 "/usr/bin/debugperl" \
"-MExtUtils::Command::MM" "-MTest::Harness" "-e" " test_harness(1, \
'inc', 'blib/lib', 'blib/arch')" t/12_nama.t

...

ok 57 - set JACK client as input
sax: JACK source port is sax_in. Make connections manually.
Track sax: source set to JACK manual port sax_in
debugperl: sv.c:6438: Perl_sv_clear: Assertion `SvTYPE(sv) !=
(svtype)SVTYPEMASK' failed.
Failed 69/126 subtests
...

Address Sanitizer shows the crash with non-debug perl:

"/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "

...
