I guess it's unrelated, but just make sure: have you compiled boost with eg++ (see https://github.com/bitcoin/bitcoin/blob/master/doc/build-openbsd.md#building-boost)?

Can you add a backtrace please?

@janstary Can you follow up with any more info?

Here is a gdb session with the crash and backtrace. This is the current git, freshly compiled on OpenBSD 6.1-current/amd64.

That seems to be the problem - these functions must always be called with a context. Strange.

Strange - I just tried to reproduce this with master, I cannot reproduce the problem. bench_bitcoin as well as the tests run succesfully.

Can you retry with master or 0.15.0rc1?

@janstary Can you either retry with master or latest release and let us know the commit id you used to reproduce?
