Script Processor: "not a function" error is intermittent/non-deterministic (4.1.0)

[musicayciencia]

I am using HISE 4.1.0, Windows standalone. Please see below my case:

getGlobalVariable turned out to need array syntax (getGlobalVariable[i]), not function-call syntax (getGlobalVariable(i)) — that part makes sense once found.

The real issue: the compiler is intermittent. The exact same, unmodified line sometimes compiles fine and sometimes throws "This expression is not a function!" — I've seen this happen even to setGlobalVariable(...) calls (which are correctly function-style). Recompiling with no code change sometimes clears the error, sometimes doesn't. It's happened in a fresh, minimal project too (not just a long-edited one), so it doesn't seem to be project corruption.

Minimal repro that has failed intermittently for me:

function onNoteOn()
{
setGlobalVariable(2, 1);
setGlobalVariable(1, 0);
}

in a Script Processor inside a Sampler's MIDI chain.

Is this a known issue with this build? Anything I should check (JUCE/compiler version, a setting, etc.) before assuming it's just flaky?

@musicayciencia First thing you should do is build HISE form the source.

Ignore the Releases section on GitHub - 4.1.0 is far too old to spend any time debugging it.

Follow the "How to Compile HISE" details further down the repo page.

@musicayciencia setGlobalVariable() isn't a HISE function, or is it a function you created? Either way, you should avoid global variables if you can.
