I worked on a transpiler from Nand2tetris assembly to WebAssembly, and had some really annoying memory corruption bug that I just couldn't solve.

That is, until I checked the program I used for testing (which I didn't write), and found the following code:

  dealloc(this)
  return this->field

My allocator, however, overwrote the field during the deallocation with bookkeeping stuff, which meant the returned value was not what the programmer intended and after a short while the program crashed.

Unlike TFA, I had the luxury of just fixing the test program.

IIRC, one of the similar old story from Raymond Chen is about SimCity 2000, that did a similar trick (free memory, then start immediately using it) that worked just fine under DOS, but was a big no-no starting with Windows 95. The game was so common that Windows had to include a special rule to make it run...
