I create a simple perl embedding code (copy-paste from documentation): 
#include <EXTERN.h>
#include <perl.h>

static PerlInterpreter * my_perl = 0;

int main(int argc, char **argv, char **env)
{
    PERL_SYS_INIT3( &argc, &argv, &env );

    my_perl = perl_alloc();
    perl_construct(my_perl);
    perl_parse(my_perl, 0, argc, argv, 0);
    perl_run(my_perl);
    perl_destruct(my_perl);
    perl_free(my_perl);

    PERL_SYS_TERM();
}

Command line: ./test -e 'print "Hello, world!"'
Works fine, but valgrind report leaks:

1225 leaked bytes on simplest example - not very good. Any ideas?

P.S.: valgrind 3.3.0 - latest release, perl 5.8.8
