Fix Strict Aliasing Violation

Even though this failed with non regression bounds on fishtest, merging
it as is to improve the current situation.

Failed Non Regression:

LLR: -2.94 (-2.94,2.94) <-1.75,0.25>

Ptnml(0-2): 553, 21228, 49811, 20730, 574

Previously we had code similar to this
```
alignas(64) std::uint8_t foo[1024];
const auto* int_ptr = reinterpret_cast<const std::int32_t*>(foo);
```

Which is a strict aliasing violation once we dereference int_ptr, which
invokes UB and causes newer gcc version to emit incorrect code.

This violation was introduced in PR #3287 and merged in commit 23c385e.
Due to aggressive compiler optimizations, users may need to include
CXXFLAGS=-fno-strict-aliasing as a build argument to ensure a correctly
functioning binary.

Also thanks to @anematode for writing parts of this and realizing this
strict aliasing violation.
