Re^3: One piece of code, two mysteries!

Ok, when I set it to 16k (16384), I got a segmentation fault. When I commented out the line entirely, it seemed to go to indefinite sleep and returned nothing to the screen. I did not even see the process in "top." I finally tried setting the stack to 65535 and got the following output.

Is that what was expected?

When I commented out the line entirely, Do you mean like this?: `#use threads stack_size => 4096;` [download] If so, you should have at the very minimum got an error: "Can't call method "async" without a package or object reference at ..."!? To disable the stack_size parameter, you should do: `use threads; # stack_size => 4096;` [download] With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

That's interesting. Yes, I commented out the entire line, but got no error message. It was simply as if the program had hung. I had to CTRL + C out of it after I had waited a couple minutes or so. (Tried again later and it went over 12 min. before I lost patience.) Just for fun, I just ran it with the "use threads;" implementation, and it gave me the exact same results as with the 64k stack size. Blessings, ~Polyglot~	[reply]
