The pad_size array is used to compute code/data/load mapping sizes for
ldelf by measuring the gaps after each PT_LOAD segment. The last entry
was hardcoded to 0, effectively ignoring the final segment’s
(p_memsz - p_filesz) - i.e. the BSS portion that exists in memory but
not in the file.
As a result, the RW mapping for ldelf was undersized: the zero-filled
area of the last PT_LOAD was not reserved, which could lead to writes
past the mapped region.
