When `const auto& r = cond ? a : b;` Becomes a Dangling Reference – 3 C++ Lifetime‑Extension Pitfalls

The article explains that although C++ extends the lifetime of temporaries bound to a const reference, this rule has three critical edge cases—returning const references from functions, binding references in member initializer lists, and using the ternary operator—each of which can produce a dangling reference and cause obscure runtime crashes.

Why a Single Warning Can Cause Xcode to Eat 6GB RAM – A Real‑World iOS Debugging Tale

An iOS team discovered that Xcode’s memory usage jumped from 2 GB to nearly 7 GB after a codebase upgrade, traced the surge to hundreds of nonnull warnings embedded in header files that inflated .dia cache files, and resolved the issue by removing the warnings, highlighting the hidden cost of ignored compiler warnings.
