QEMU

When creating a core dump, QEMU uses the function [vma_dump_size] (https://github.com/qemu/qemu/blob/5134cf9b5d3aee4475fe7e1c1c11b093731073cf/linux-user/elfload.c#L4059-L4082) to decide whether a given memory segment is included in the dump. Which it is at liberty to do since the man page states that such advice is only a hint.

/*
 * Calculate file (dump) size of given memory region.
 */
static size_t vma_dump_size(target_ulong start, target_ulong end,
                            unsigned long flags)
{
 /* The area must be readable. */
