Hello i have a problem with reading QR codes.
I am using FMXTestApp

it happens every time (sometime on first read, sometime on X read) and the error is in this 

Unit - ZXing.Common.BitArrayImplementation
Function - function TBitArrayImplementation.getNextUnset(from: Integer): Integer
Code - currentBits := currentBits and (not( (1 shl (from and $1F)) - 1))  (line 161)

I have 3.9.4 version Android 32
