    This is really neat. I changed the quality value to 6: clang took ~20 minutes to compile and it used around 32GB of RAM. The resulting executable is 13KB, and it generates a 4KB image as output.

    Here's a link of the output image: https://imgur.com/cUdForu

    Just as a FYI, this takes a while to compile:

      $ pbpaste | time clang -x c -
         99.35 real        82.72 user         9.94 sys
    If you're using iTerm, you can pipe the output of the program to imgcat to see the result without leaving your terminal.

    Can we please have constexpr in C 2x to put an end to this madness?

    $ cc -E cursed_mandelbrot.c | wc 546 8804289 76385728

    The pre-processor outputs 76,385,728 chars on 546 lines

    Off topic but I think some of you fellow math geeks will get a kick out of the Mandelbrot Set song by Jonathan Coulton.

    I clicked on it and expected an IOCCC contest entry or something...

    Getting

    "virtual memory exhausted: Cannot allocate memory"

    when trying to compile :/

    MSVC 2017 x64 (v19.15.26730) fails with Error C1060: compiler is out of heap space.
