Segfaults are the result of programming bugs, or sometimes caused by not correctly handling unexpected input (which is essentially also a bug).

Unfortunately, it's next to impossible to debug such problems without being able to reproduce them.

In other words, it would help if you could reduce the input to a minimal case the allows to reproduce the issue, and then submit a bug report to YAML::XS, as the author of the module can probably help better here.

Until then, you might want to try the non-XS version of YAML instead.
