ArrayIndexOutOfBoundsException during WASM_GC generation

[kenchis]

I am not sure, but i assume i hit the maximum number of function parameters for my oscilloscope view?

` @import(module = MODULE_NAME, name = "processOsc")
@JSBody(params = { "sidNum",

		"wav0", "wav0Len", "wav0Txt", "wav1", "wav1Len", "wav1Txt", "wav2", "wav2Len", "wav2Txt",

		"env0", "env0Len", "env0Txt", "env1", "env1Len", "env1Txt", "env2", "env2Len", "env2Txt",

		"frq0", "frq0Len", "frq0Txt", "frq1", "frq1Len", "frq1Txt", "frq2", "frq2Len", "frq2Txt",

		"vol", "volLen", "volTxt", "res", "resLen", "resTxt", "fil", "filLen", "filTxt"

}, script = "processOsc(" + "sidNum, "

		+ "wav0, wav0Len, wav0Txt, wav1, wav1Len, wav1Txt, wav2, wav2Len, wav2Txt, "
		+ "env0, env0Len, env0Txt, env1, env1Len, env1Txt, env2, env2Len, env2Txt, "
		+ "frq0, frq0Len, frq0Txt, frq1, frq1Len, frq1Txt, frq2, frq2Len, frq2Txt, "
		+ "vol, volLen, volTxt, res, resLen, resTxt, fil, filLen, filTxt)")
public static native void processOscJS(int sidNum,

[konsoletyper]

Exactly. I never thought that anyone hit 32 parameters limit, and never introduced some kind of error reporting there. So it's just crashing in this case.

[kenchis]

I did hit the limit ;-)
But its not the best programming style, absolutely.
All that is part of twelve canvas per sound chip oscilloscope view.
However i worked around it.
