Re^6: Syntax error makes perl hang

Except that 'aa' ..'aaaaaaaa' which works is a bigger array than 'pfo' .. 'pctpfo', unless I'm completely misunderstanding how it increments them. I'm guessing there is some kind of optimization in that case? ... Either way why does Perl still allocate the memory during the -c check? (my machine crashed while using -c)

If it is just the size I suppose there's not a bug per se, but it would be nice if there was some kind of brake to keep Perl from running away with all the memory. I still say there is a bug though, at the very least -c shouldn't allocate the memory.

perl attempts some basic optimisations during the compile phase. One of which is to precalculate constant lists. Since both arguments to the range operator are constant the list it produces will be constant and can be precomputed.	[reply]

Well I was going to try this out and give some actual figures, but when I got to `'pfo' .. 'pctpf'` it swallowed all the swap and I decided to reboot rather than wait for it. `'aa' .. 'aaaaa'` was fine - producing 475229 elements. /J\	[reply] [d/l] [select]
