I can confirm the behaviour. OS is Linux, Ubuntu 22.04.

With Perl 5.34.0:

$ time perl -wE 'my $x = `cat 2`'

real    0m4.558s
user    0m0.802s
sys    0m3.192s

$ time perl -wE 'my $x = `cat 1`'
Segmentation fault (core dumped)

real    1m28.649s
user    0m0.430s
sys    0m2.341s

With Perl 5.39.10: 

$ time blead -wE 'my $x = `cat 2`'

real    0m8.851s
user    0m0.980s
sys    0m3.795s

$ time blead -wE 'my $x = `cat 1`'
Segmentation fault      (core dumped)

real    0m5.694s
user    0m0.397s
sys    0m1.378s

So the newer perl still fails, but much faster :-)

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
