Each nesting level increases the stack and the number of previous starting events that the parser has to check. The default maximum is 1000 and can be set via yaml_set_max_nest_level() I also added new options to run-parser and run-parser-test-suite: * --max-level: you can now try out this feature on the command line * --show-error: By default, run-parser doesn't show errors. The new option helps with debugging
