assert error in eventcore #2

[Sandman83]

I'm not sure, whether the eventcore is the culprit, or something of my program.
But the stack trace does not contain anything of mine, so I post it here, down below.
If you need my code, it is not available yet, but it will be later.

Assertion failure @/Users/alex/.dub/packages/eventcore-0.8.39/eventcore/source/eventcore/drivers/posix/events.d(224): Invalid eventID.

Ok... I removed the dependency on vibe from my library. Now, it works.
My ActivityManager shows a rising memory usage while using vibed, so I assume a memory leak. Maybe, this helps somehow.
