Wrapped strings cause assert failure

Issue #10 new
Stanisław Pitucha created an issue

Hi, I found an edge case in scanner that results in an assert() failing. The document is:

   def: 'xxx
'  ghi: 'yyy'

And the issue is caused by that line-wrapped 'xxx'. The next entry needs to be aligned with the first otherwise it's just a normal parsing failure. Result:

[1] Parsing 'crashtest': lt-run-parser: scanner.c:1113: yaml_parser_save_simple_key: Assertion `parser->simple_key_allowed || !required' failed.

0.1.5 and 0.1.6 are affected.

(found with AFL fuzzing)
