That's due to the stack being too small on Windows, and currently we don't have a fix for it. BTW, the unit tests are disabled for McEliece on Windows due to the exact same reason.

So are we saying that McEliece basically doesn't work in Go on Windows? Is that already mentioned in the documentation of the wrapper? Same with the other test exclusions (HQC on Darwin)?

@baentsch just saw this. Yes, doesn't work, and no, not yet mentioned in the documentation.
