Re: coroutines

Thanks for the reply Zachary.

I think I should clarify what is happening before going any further.

When I run the sieve script, It prints out prime numbers up to 53 and 
then it just sits there doing nothing. I have to hit ctrl-c to kill the 
process. I tried making LUAI_MAXVARS and LUAI_MAXUPVALUES much smaller 
but that did not seem to make a difference. Here is an example of what 
is printed:

/home/lua> lua sieve.lua
2
3
5

...

43
47
53
pid 23: failed 2
/home/lua>

Now I also have a few versions of the sieve script that I modified 
slightly. I added some print statements to see if I could debug the 
script that way. Anyway, when I run those version of the script it 
prints out prime numbers but it never gets as far as the original 
script. Here is an example of what is printed with only a couple minor 
changes (I'm sure you can guess what they are):

/home/lua> lua sieve-t.lua
i=      2
n=      2
i=      3
n=      3
i=      4
i=      5
n=      5
i=      6
i=      7
n=      7
i=      8
i=      9
i=      10
i=      11
n=      11
i=      12
i=      13
n=      13
i=      14
i=      15
i=      16
i=      17
n=      17
i=      18
i=      19
n=      19
i=      20
i=      21
i=      22
i=      23
n=      23
i=      24
i=      25
i=      26
i=      27
i=      28
i=      29
n=      29
i=      30
i=      31
n=      31
i=      32
i=      33
i=      34
i=      35
i=      36
i=      37
n=      37
i=      38
i=      39
i=      40
i=      41
n=      41
00      42
00      43
n=      43
pid 24: failed 11
/home/lua>

I should point out that I did not have to ctrl-c to kill the process for 
this version of the script, it exits on its own. Any idea what "failed 
11" means?

The last few lines are interesting, notice how "i=" somehow magically 
turned into "00". Other variations of the script all seem to have there 
own unique weirdness.

So, any idea's on where I can go from here?
