HISE crashes when setOnGridChange(true, onGrid) is used

[MidiMinion]

I can run the following code without any issues, but when I change the last line to true (so the function runs synchronously), HISE crashes immediately.
Has anyone else experienced something like this?
I’m wondering if this is a known issue or if I might be doing something wrong.

const var th = Engine.createTransportHandler();
th.setSyncMode(1);
th.setEnableGrid(true, 5);

inline function onGrid(grid) 
{
    Console.print(grid);
}

th.setOnGridChange(false, onGrid); // works fine
// th.setOnGridChange(true, onGrid); // crashes HISE
