SimpleModelicaParser does stack overflow on huge arrays

[Adrian Pop]

Basically it does diffModelicaFileListings on a file with a *HUGE* diagram annotation.

This needs to be rewritten somehow so that it doesn't blow up the stack:

  elseif id==TokenId.LBRACE then
    (tokens, tree) := scan(tokens, tree, TokenId.LBRACE);
    (tokens, tree, b) := LA1(tokens, tree, {TokenId.RBRACE}); // Easier than checking First(expression), etc
    if not b then
      (tokens, tree) := function_arguments(tokens, tree);
    end if;
    (tokens, tree) := scan(tokens, tree, TokenId.RBRACE);

The problem is that function_arguments is self recursive:
