Why didn't this fail when the PR was tested? Is a different testsuite executed for PRs and after a merge?

Anyway, this doesn't seem to be a new bug my patch introduced but a bug that wasn't known (tested) before: passing float and double through varargs. I added a test each:

1. passing double: nothing special happening, just wasn't tested, always worked in JNA
2. passing float: needs to be promoted to double (also on ARM afaics), my patch implemented that
   Since both are failing I assume there's a basic problem. Maybe a libffi bug? Or the rasberry Pi doesn't support this and the test needs to be disabled for this target?
   How to proceed best? I don't have access to a raspberry Pi.

It’s not a bug in your code, it’s an existing bug exposed by the tests you added (that’s a good thing).

We have platform-specific tests run on merge into master (and PRs on the main project), these run on linux, mac, and raspberry Pi. Other platforms get run ad hoc before release.

I’ve put up a PR to address the ARM issue - it actually uses a different ABI when using varargs.
