Description

With aligned_alloc() in the C11 standard, free() is called to free memory, rather than an equivalent aligned_free().

We should update our library with some logic that can be used to correctly call aligned_free() if free() is used instead.

Contributor guide

Research direction
Examine the current implementation of aligned alloc and free to determine how to detect when free() should call aligned free() instead. Introduce a mechanism (e.g., storing alignment info in the allocation header) to differentiate between aligned and non aligned allocations.
