Vim hangs in infinity loop with printf (language: C) command

[TornaxO7]

This is a minimal example in C:

#include <stdio.h>
#include <stdlib.h>

int main () {

    while (1) {
        printf("Houston, we've a problem...\n");
    }

    return EXIT_SUCCESS;
}

If I run it with this command:

:AsyncRun -mode=async -cwd="$(VIM_FILEDIR)" -save=2 gcc % && ./a.out

than vim hangs up and the memory usage increases until my pc hangs up unless I kill the process manually.

The moment when you see the output at bottom appears if I hit Ctrl + c. I can't stop it with :AsyncStop since (neo)vim is stuck.

try

:AsyncRun -mode=term -pos=tab -cwd="$(VIM_FILEDIR)" -save=2 gcc % && ./a.out

It's working with your command now and I can cancel it with Ctrl+c, thanks! But it'd be nice if I could see the output at the bottom ^^ should I close this issue?

neovim's quickfix is inefficient, and job api is lack of flow control. asyncrun has nothing to do with it.

Ok, thanks for the information!
