The tests fail

https://github.com/hajimehoshi/purego/actions/runs/13750780953/job/38451482165

=> go test CGO_ENABLED=0

Anything else you feel useful to add?

No response

[hajimehoshi]

The mysterious thing is, the test does not 'fail' with a red signal, but says 'fail' in the output.

Perhaps the size of one of the structs in Cgo doesn't match. Perhaps the non failure is bc it's inside a script?

[hajimehoshi]

For the test script, just adding -e should work.

diff --git a/.github/scripts/bsd_tests.sh b/.github/scripts/bsd_tests.sh

and unfortunately, I found another issue on FreeBSD...

I'll create another issue.
