" summary

A short C++ lab reproduces a surprising static-linking bug: adding an Evil Twins and the Secret Lives of Linkers! farewell library introduces duplicate inline definitions of a helper, the final binary resolves one copy arbitrarily and the program intermittently aborts. The demo uses object files, symbol tables and objdump to show link-order changes can silently fix or break the run, removing inline triggers a duplicate-symbol linker error, and renaming fixes it deterministically.
