[erlang-questions] Compile Question

[Michael Schmidt]

Thanks!  I think you might be onto something.  We use a lot of funs in our resolve functions.  Is the limit per-function?  Or per-function-head?

  Try reducing the complexity of this function.

  Instruction: {move,{x,0},{y,1555}}
...
Poking around, there is indeed a list of 776 items that generates 2 function defs each, which gives us a final AST list of approx 1552.  I assume this is related to the {y,1555} in Error.

Can lists:each() not handle lists longer than 1024?  What am I missing?



The limit is on the number of funs that can be exported by a single function. Each function gets an id like `#Fun<mod.9.54861464>` where the second integer (9) is a counter of the number of anonymous functions/closures within a single function. You probably overflow that counter.
