Just wanted to let you know that I've found the solution already. After
playing around with it I have discovered that fix is in adding
ENTER;SAVETMPS;FREETMPS;LEAVE fixes the problem.
So
for(i = 0; i < 1000; i++)
{
SV * sub;
char text[256];
ENTER;
SAVETMPS;
sprintf(text, "$sub = %d;", i);
sub = eval_pv(text, TRUE);
FREETMPS;
LEAVE;
sleep(1);
}
does not leak memory. Anyway, thank you for all replies.
