# Analysis Results
## Dependence on predictable environment variable
- Type: Warning
- Contract: WeakRandom
- Function name: `_function_0xe9874106`
- PC address: 1285

### Description
In the function `'_function_0xe9874106'` the following predictable state variables are used to determine Ether recipient:
- block.coinbase


In *<TESTDATA>/inputs/weak_random.sol:47*

```
winningAddress.transfer(prize)
```
## Ether send
- Type: Warning
- Contract: WeakRandom
- Function name: `_function_0xe9874106`
- PC address: 1285

### Description
In the function `'_function_0xe9874106'` a non-zero amount of Ether is sent to an address taken from storage slot 0.
There is a check on storage index 0. This storage slot can be written to by calling the function 'fallback'.

There is a check on storage index 1. This storage slot can be written to by calling the function 'fallback'.
There is a check on storage index 1. This storage slot can be written to by calling the function 'fallback'.

```
## Exception state
- Type: Informational
- Contract: WeakRandom
- Function name: `fallback`
- PC address: 356

### Description
A reachable exception (opcode 0xfe) has been detected. This can be caused by type errors, division by zero, out-of-bounds array access, or assert violations. This is acceptable in most situations. Note however that assert() should only be used to check invariants. Use require() for regular input checking.

## Integer Overflow 
- Type: Warning
- Contract: WeakRandom
- Function name: `_function_0xe9874106`
- PC address: 1216

### Description
A possible integer overflow exists in the function `_function_0xe9874106`.
The addition may result in a value higher than the maximum representable integer.
