libjack64.dll crashes on application startup

I've built a small test application (64 bit) using simple_client.c of the jackaudio/example-clients respository. On Linux and Mac it is working like expected but on Windows 10 it crashes right after starting the application.

Exception thrown at 0x0000000069A2F26B (libjack64.dll) in Jack2SimpleClient.exe: 0xC0000005: Access violation reading location 0xFFFFFFFF95A71BEC.

It does not matter if the JACK server is running or not.
