Panic uninitialised linked hash map

[martinellison]

When I try to deserialise YAML using serde, I get the following traceback:

thread 'test::simple' panicked at 'attempted to leave type `linked_hash_map::Node<yaml::Yaml, yaml::Yaml>` uninitialized, which is invalid', /home/martin/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/mem/mod.rs:658:9

Just solved a similar problem.
For me it happend with rust version 1.48.0
After moving back to 1.47.0 it was solved

I've had this issue and version 0.4.5 fixes it, thank you very much!
