Unstable results on macOS

[hurricup]

Recently I started to expand integration tests for my Perl plugin for IntelliJ IDEA and found out that for some reason profiler produces unstable results in different runs. Ubuntu and Windows are fine.

• perl-5.36.0
• latest NytProf

Here is my test script:

sub something {
    my $scalar = 1;
    if ($scalar > 2) {
        print "false";
    }
    elsif ($scalar < 2) {
        print 'true';
    }
    print 'done';
}

BEGIN{
    print 'begin block';
}

print 42;
something();

END{
    print 'this is the end';
}

And here are 2 different runs stmts=0:calls=2:savesrc=0:slowops=1:sigexit=1:addpid=1:start=init:
