Bash Version: 4.4 Patch Level: 23 Release Status: release Description: If I have a variable with the value 0 assigned to it incrementing it causes the return code to be 1, even though the variable has been incremented successfully. This only happens if the value of the variable is 0. With positive and negative values this bug is no present.
