Describe the bug I'm trying to port Bear to OpenBSD. While the build process is 99% fine (the only small issue to be reported separately), trying to run bear -- ... gives error. I'm not asking for a fix, but for a clue, what could went wrong.

To Reproduce Build Bear from port in openbsd-wip repository.

Expected behavior Bear starts and does something useful.

Environment:

Additional context The problem happens with any command specified after the "--". The verbose log (with environment variables tweaked a bit for privacy reasons) is here:

If I create the problematic file myself, it gets catched and read by Bear, and then gets removed before Bear exits.

Before you send...

... and only after filling the issue I've realized that there is coredump of intercept being generated silently. So now I have the clue. Sorry for the noise. :)
