Guard PE32 export copies when the companion omits plaintext stub data. Reserve the complete export directory during compaction and validate file backing before overlaying it to prevent writes into the next section.
Add regression coverage for zero-filled export space, invalid directory ranges, and truncated source or destination sections.
The packer demotes the four base-relocation entries covering the TLS
directory's VA fields to IMAGE_REL_BASED_ABSOLUTE padding, because its
own loader fixes TLS up by hand. Restored verbatim, a DLL mapped off its
preferred base keeps stale VAs in its TLS directory and the OS loader
faults in LdrpAllocateTlsEntry while writing the TLS slot index through
the unrelocated AddressOfIndex (observed as a 0xc0000005 startup
failure).
Walk the restored BaseReloc blocks and promote those entries back to
IMAGE_REL_BASED_HIGHLOW, gated on is_dll so EXE output stays
byte-identical.
