Compound literals are especially pernicious[1] because GCC and (I think) clang support them in C++ mode, but they have expression lifetime like C++ temporary objects, not block lifetime as in C. That's a guaranteed recipe for dangling pointers and stack smashing/snooping. [1] From a C++ is just a C superset perspective. In C compound literals are awesome.
