strictasm_diff_ossfuzz: crashing test case causes `Interpreted traces for optimized and unoptimized code differ.`

## Description

Hi! We found a crashing test case when testing with the `strictasm_diff_ossfuzz` fuzzing driver that reports `Interpreted traces for optimized and unoptimized code differ.`

## Steps to Reproduce

PoC:
```
{mstore(0, 7)
sstore(0, mload(0))
mstore(sub(0, 1), sub(0, 1))
sstore(1, mload(sub(6, 1)))
}
// ----
// Trace:
// Memory dump:
// 0: ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff07
// FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFE0: 00000000000000000000000000000000000000000000000000000000000000ff
// Storage dump:
// 0000000000000000000000000000000000000000000000000000000000000000: 0000000000000000000000000000000000000000000000000000000000000007
// 0000000000000000000000000000000000000000000000000000000000000001: ffffffffffff{}}
```

Start with the strictasm_diff_ossfuzz driver and run the supplied PoC, then compare the interpreted traces for optimized and unoptimized code. Trace the mismatch through the compiler's optimizer and interpreter paths; done means the driver no longer crashes or reports differing traces for this case.
