overindented (likely valid) YAML causes abort #223
Description
version: v0.4.0
compiler: clang-13
os: ubuntu 20.04
A bit of a strange case, but after checking a few yaml validators online, this yaml seems valid, but causes error:
auto yaml = R"config(
A:
- 1
- 4
B:
- 2
- 3
)config";
ryml::Callbacks callbacks{};
callbacks.m_error = [](const char *msg, size_t msg_len, ryml::Location location, void *)
{
throw std::runtime_error({msg, msg_len});
};
ryml::Tree tree{callbacks};
ryml::parse_in_arena(ryml::to_csubstr(yaml), &tree);
std::cout << "parsed:" << std::endl << tree << std::endl;
The output is:
_deps/ryml-src/ext/c4core/src/c4/substr.hpp:207: ERROR: check failed: i >= 0 && i < len
SIGABRT - Abort
(also fails to trigger the callbacks configured on tree)
yes, I'm aware that the yaml created by that multiline string literal is actually this (which yaml validators seem to think is fine):
A:
- 1
- 4
B:
- 2
- 3

Is there something I'm using incorrectly? or is this a bug?
