when i openStream,it will crash some time in VectorImpl::_grow()

[jie545098983]

Mycode:
bool Recorder::create(int sampleRate, AudioStreamCallback *callback) {
mSampleRate = sampleRate;
AudioStreamBuilder builder;
builder.setDeviceId(oboe::kUnspecified);
builder.setChannelCount(1);
builder.setSampleRate(sampleRate);
builder.setCallback(callback);
builder.setPerformanceMode(PerformanceMode::LowLatency);
builder.setSharingMode(SharingMode::Exclusive);
builder.setSampleRateConversionQuality(SampleRateConversionQuality::Medium);
builder.setFormat(oboe::AudioFormat::I16);
builder.setDirection(oboe::Direction::Input);
builder.setAudioApi(oboe::AudioApi::Unspecified);

Result result = builder.openStream(&mRecordingStream);
if (result != Result::OK) {
    return false;
}

auto setBufferSizeResult = mRecordingStream->setBufferSizeInFrames(
        mRecordingStream->getFramesPerBurst() * 2);
if (setBufferSizeResult != Result::OK) {
    return false;
}
return true;

}

when i createRecorder,it will crash like this:
Abort message: 'Assertion failed: editable == NULL'

It may be related to a memory allocation failure.

Does this happen after working OK, many times?

Are you closing the stream?

We need more information. Can you please fill in some of the information below.

Android version(s):
Android device(s):
Oboe version:
App name used for testing:
(Please try to reproduce the issue using the OboeTester or an Oboe sample.)

[jie545098983]

yes，it work ok at first time , i used the method mRecordingStream->stop() and mRecordingStream->close() to stop the stream. after some second i create the stream again,it will crash some time
Android version(s): 9
Android device(s): mi 6
Oboe version: 1.3.3

@jie545098983 by putting your code into a small app, I could not see it happening on Pixel 3a XL. if your app is simple one, could you post it somewhere or via email? if it is a big, please share the binary, we could try it out. The sample rate I used is 44100Hz ( device's native sample rate is 48000Hz ), what is the sample rate you are trying to convert? What happen if you do not let it re-sample ( do not set the sampleRate )?

Is your callback object for recording stream the same one for creating all recording streams?

if code or binary is not possible, probably file a bug in public issue tracker and upload a bugreport there? please update here with your created issue number here; you might also do a quick profile to check on memory usage with profiler tool in Android Studio.

thank you for file the issue, it is important one.
