Minimal repro

int16_t samples[260] = { 0 };
volatile uint16_t sampleReadStartIdx = 0;

void setup() {
}


void loop() {
  samples[sampleReadStartIdx] = samples[sampleReadStartIdx];
}

Error compiling for board ATtiny3224/1624/1614/1604/824/814/804/424/414/404/214/204.

Compiling for ATtiny804 with IDE 1.8.19, megaTinyCore 2.6.10

Of note

making sampleReadStartIdx non-volatile makes the error go away.
removing either the read or the write of samples in loop() makes the error go away

Of course, the second I said that, I realized I am using >512 of storage for that array… nevermind
