Array initialization trigger the issue of invalid opcode=stelem.i1

[pengzeshan]

Here is the simple code to trigger the issue: namespace ConsoleApp1 { class Program { static void Main(string[] args) { } public byte[] GetArray(int value) { byte[] thirdArray = new byte[value]; for (int i = 0; i < value; i++) thirdArray[i] = 11; return thirdArray; } } } Error message: Severity Code Description Project File Line Suppression State Error MSB4018 The "Translate" task failed unexpectedly.
