WebMay 5, 2024 · GCC has long implemented a warning to detect these kinds of bugs: -Wfree-nonheap-object. But until GCC 11, the option detected only the most obvious bugs involving the free() function—basically just passing the address of a named variable to it. GCC 11 has been enhanced to check every call to every known C or C++ deallocation function. WebDifferent compilers vary in how complex a function they can manage to inline. Mainstream C++ compilers like Microsoft Visual C++and GCCsupport an option that lets the compilers automatically inline any suitable function, even those not marked as inlinefunctions.
