Native crash while decoding contact qr code

[code-schreiber]

I found a native crash while decoding an specific image and can't figure out what exactly makes it happen. My assumption is that, because it is a contact qr code (VCARD), the information contained in the qr code is incomplete or corrupt in a way and android-vision doesn't cope with it well.

Tested on an emulator with API 27 x86, but originally experienced this same crash on a Nexus 9.

To reproduce

Dependency

implementation "com.google.android.gms:play-services-vision:11.8.0"

Code to detect

BarcodeDetector detector = new BarcodeDetector.Builder(context)
        .setBarcodeFormats(Barcode.QR_CODE | Barcode.PDF417 | Barcode.AZTEC)
        .build();
if (detector.isOperational()) {
    Frame frame = new Frame.Builder().setBitmap(bitmap).build();
    SparseArray<Barcode> detectedCodes = detector.detect(frame); // Crash
}

Bitmap being scanned

Content of bitmap

VERSION:3.0
N:Lastname;Firstname
FN: Firstname Lastname

TEL;;TYPE=voice,cell:+1 123456
END:VCARD

This is the complete stacktrace
