Writing Bounds-Safe Code in C with Arrays

  Good, succinct and to-the-point article. References: GCC: https://gcc.gnu.org/onlinedocs/gcc-6.3.0/gcc/Instrumentation-Options.html https://gcc.gnu.org/onlinedocs/gcc-6.3.0/gcc/Instrumentation...

  Rare to see VLAs described as "one of the coolest features of C".

    Note that this is about pointers to variably length arrays, and not a VLA on the stack. But both are cool features. Bounds checking would be further ahead, if VLAs did not get a bad reputation from poor compilers that did not do stack probing.
