Your comment gave me quite a fright, as I run/maintain in-house code that uses flexible arrays in ways not dissimilar to your examples. Testing with clang and gcc gave me exactly the same numbers you ...

This is an excellent question. Zero-length arrays, also known as flexible arrays, are used to implement variable-length arrays, primarily in structures. That's a little confusing, so let's look at an ...

Kees Cook has posted a detailed document describing the work to improve safety of flexible-length arrays in the kernel. Converting such codebases to use “modern” language features, like those in C99 ...
