The parser can overflow the stack on relatively small code, like 100 nested [[[...]]] expression. Possible solutions are:

  • use explicit stack on heap
  • Rewrite the expression parsing part to be smarter instead of 10 levels of recursion.

In case of overflow on a too long expression, proper error should be emitted instead of crashing
