Description

`io_lib:format/3` crash with `chars_limit` set for complex data structure when format uses new formatter feature `~0p`. Also I found that minor modification in format or in value passed to first `~0p` parameter eliminates crash. Removing `chars_limit` also eliminates crash.

You can find code that crash ErlangVM attached to this issue.
