Opus 1.3.1 crashes on iOS 18.

This stack trace looks strange.

This is my decoded code

int32_t CodecOpus::OpusToPcm(uint8_t * bufferOpus, uint32_t opusSize, uint16_t * bufferPcm, uint32_t pcmSize)
{
	int usingFec = 0;
	uint8_t* inputBuffer = bufferOpus;
	int32_t inputSize = opusSize;

    int32_t outputSamples = pcmSize / (2 * _channelCount);
	if (_lastFrameSize != 0) {
		usingFec = 0;
		inputBuffer = _lastFrameBuffer;
		inputSize = _lastFrameSize;
	} else { // last frame has lost
		usingFec = 1; // use current frame to recover last frame(using fec)
		outputSamples = _samplesPerFrame;
	}
	int32_t decodeResult = opus_decode(_decState, (const uint8_t *)inputBuffer, inputSize, (int16_t *)bufferPcm, outputSamples, usingFec);
	if (bufferOpus != NULL && opusSize <= kOpusMaxFrameSize && opusSize > 0) {
		memcpy(_lastFrameBuffer, bufferOpus, opusSize);
		_lastFrameSize = opusSize;
	} else {
		_lastFrameSize = 0;
	}

	if (decodeResult > 0) {
		return decodeResult * 2 * _channelCount;
	}
	return decodeResult;
}
