Random crashes when quickly printing many millions of lines in terminal

ee068bfc-f4ec-49fa-9b22-fe37962b729b.dmp Type: Bug

Little C program to print 200 million lines did it first try on Insiders:

#include <stdio.h>
int main() {
    int i;
    for (i = 0; i < 200000000; i++) {
        printf("%d Hello, World!\n", i);
    }
    return 0;
}

gcc main.c
./a.out

My current project prints out tens of millions of lines and was crashing VScode maybe one run out of half a dozen. I thought it was memory related so wrote a test program with no memory handling. 20 millions lines wasn't enough to reproduce it but 200 million crashed VScode so I tried Nightly and the same.

There is no error or warning of any kind. VScode just suddenly vanishes.

I've just reproduced it with --crash-reporter-directory and attached the resulting .dmp

Just reproduced using code --disable-extensions too.

Just ran into this issue running on an m1 Mac, the unceremonious crashing is unfortunate
