"As a general rule: If you have a question about why some code doesn't do what you expect. Post the code (or the smallest sample program that demonstrates the problem)."
Ok, agree. But i must say that this question is not about one piece of code that doesn't want to work. This question is about common problem in perl(sorry) - signals and malloc(you can of course call it more smartly, kinda low level interaction of perl and cpp methods or what ever). I saw questions from people about this(google,you know e.t.c.), but (i)didn't find any clear answer. So i didn't want to bother anyone with the another snippet with the same problem. Just wanted a quick answer(help).
