In 2.35 changes were made to localise %SIG in the Safe Compartment.
This clobbers signal handlers already setup,
With safe 2.33
perl -MSafe -e '$f = Safe->new; warn "Then\n"; for ( keys %SIG ) { $SIG{$_}
= $_; warn " \$SIG{$_} => $SIG{$_}\n" } $f->reval("1 + 1"); warn "\nNow\n";
for ( keys %SIG ) { warn " \$SIG{$_} => $SIG{$_}\n" }';
