Surprising test failure on FreeBSD

[pizzamig]

Running cargo test on FreeBSD surprisingly fails. I say surprisingly, because I don't see operating system dependent section that can cause it. I guess, that deserialization is the problem. Here the output:

running 11 tests
test adjacently_tagged::test_json_serialize ... ok
test adjacently_tagged::test_bincode_round_trip ... FAILED
test adjacently_tagged::test_json_deserialize ... FAILED

test marker_traits::deserialize ... ok
test marker_traits::test_serialize ... ok
test internally_tagged::test_bincode_round_trip ... FAILED
test internally_tagged::test_json_deserialize ... FAILED

failures:

Any idea why it's happening? I'd more than happy to contribute with a patch, but I don't know where to start.

I've found the crate OS dependant: ctor , used by inventory Once ctor has FreeBSD support, all tests are fine. I'll send a PR

[pizzamig]

The crate ctor has a new version (0.1.12) that fixed the issue, not tests are happy
