I'm sending all the .i* and not only the one were the crash occurs
(knowledge/evaluation_function.ii).

The crash happens in the lines that look like (which I guess are not standard):
template <x, y, ...>
int outer_func(...) {
...
   var = (x == CONST ? func<a, b, c> : func<d, e, f>)(arg1, arg2, ...);
...
}
