Fun facts:
-
I literally found it on pixiv; it turns out that there are a few memes on it
-
on C-chan’s bra is written “CC”, which reads like “sisi” which in turn means “oppai” (i.e. tits) in russian.
-
sasachka (artist’s nickname) means “sucker” (i.e. lolipop), not “It’s difficult” as google image translator thinks
-
there is a pacman instead of amogus.

There is one more intresting fact. If you use
-O3
flag (for clang-O1
,-O2
, …) compiler performs tail recursion optimization and transforms the recursion into an infinite loop, so there is no stack overflow.Assembly
gcc -O0

It’ll fit.
gcc main.c && ./a.out
Compiler will probably just create an endless loop due to tail recursion. Try “return main()+1” to blow the stack, and use “-O0” to be sure.
