Chunk

Enumerations

enum Origin : u8
Name Value Comments
Malloc 0

malloc, calloc, realloc
New 1

operator new
NewArray 2

operator new []
Memalign 3

aligned_alloc, memalign, posix_memalign, pvalloc, valloc
Size 0x10

Verify size parameter.
Align 0x20

Verify align parameter.

Note that in an ideal world, `State` and `Origin` should be `enum class`, and

the associated `UnpackedHeader` fields of their respective enum class type

but https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61414 prevents it from

happening, as it will error, complaining the number of bits is not enough.
