[Bug report] GMS Barcode scanning crash native 100% on some image resolution/ratio

[ninh-huynh]

Describe the bug

Our app currently experiences a high number of native crashes on production. On Firebase Crashlytics, the stacktrace is like this

          Crashed: Thread: SIGABRT  0x0000000000000000

#05 pc 0xc96fc libbarhopper_v3.so (BuildId: 8d12baa81fff4118463416cb66639c20)

After some investigation, we can reproduce the crash 100%. It seems that some bitmap resolution/ratio would cause this native crash. (For example, 1366 x 32)

Here is the stacktrace from logcat

To Reproduce

1. Create a new bitmap with size 1366 x 32
2. Scan the bitmap by using MLKit Barcode scanning API

Code snippet that be able to reproduce 100% the crash

val options = BarcodeScannerOptions.Builder()
            .setBarcodeFormats(Barcode.FORMAT_QR_CODE)
            .build()

val scanner = BarcodeScanning.getClient(options)

val bitmap = createBitmap(1366, 32, Bitmap.Config.ARGB_8888)

val task = scanner.process(bitmap, 0) // <== Crash
val result = Tasks.await(task)
scanner.close()

Expected behavior
Scanner return result with empty list (without any native crash)
