This file documents which fields can be safely corrupted, overlapped, or filled with code, while still being loadable by GNU ld.so via LD_PRELOAD. Information gathered via experimentation. This list may be incomplete.
A checkmark means this field is ignored, a plus means part of the field is ignored. offsets are in hex.
