in reply to YAML::XS Load/LoadFile error

It's not YAML::XS signaling an error in the YAML, it's Perl signaling an error in YAML::XS.

What version of YAML::XS are you using? Try upgrading it, for starters.

    Yeah, I follow this is a problem in the module, not my code or the data structure, which is why I'm curious. This is the "latest", YAML::XS 0.34.

    Line 70 just calls YAML::XS::LibYAML, which is the C executable.

    Like I said, it would not take me long to do this by hand or another way -- JSON, XML, Storable, it doesn't matter -- just this seems excessively pathetic...

      Bugs are annoying, but pathetic? That's an odd characterisation, especially considering we have no idea what the bug is.

      Line 262 is a blank line. It's surely coming from what I see as line 265: 

          /* Get each key string and value node and put them in the hash */
    while ((key_node = load_node(loader))) {
        assert(SvPOK(key_node));                  <---------------
        value_node = load_node(loader);
        hv_store_ent(
            hash, key_node, value_node, 0
        );
    }

      It's expecting load_node to return a scalar already containing a string, but a check finds it doesn't. What does that mean exactly? The module's author could probably tell you faster than I could.

        Hmph. Made me wonder if 'undef' hash keys could be an issue but they test fine. Maybe I'll inquire. I have used this somewhat before, it always seemed simple and trouble free.
