Type: Debugger

i want to debug child process created by fork() and i use "-exec set follow-fork-mode child" before the fork() is called, but i found it doesn't work at all, it can't hit any break point in child process. Then i use the simple program in #511 to test, not work too.The answer in #511 doesn't work too.( "setupCommands": [
{"text": "-gdb-set follow-fork-mode child"}
])

simple program that i use to test(see #511):
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
pid_t pid = fork();
if (pid != 0) {
printf("Main process\n");
} else {
printf("Forked process\n");
}
return 0;
}

launch.json:
{
"version": "0.2.0",
"configurations": [

"text": "-enable-pretty-printing",

}

}

Yes, actually the breakpoint is hit in my case (according to DEBUG CONSOLE), but VSCode UI is not reacting on attaching and detaching of child process with actual breakpoint.

@msvaillant I can confirm I get the same result too, breakpoint is hit (and thus execution is stopped) but the UI does not react.
I have tested on 1.32.0-insider (2e4d4a6bb16a65303b460795fa4ac734f9aea43e) and 1.31.1 (1b8e8302e405050205e69b59abb3559592bb9e60)

Ok, I decided to try some old versions to see if I could pinpoint the version where it went wrong, as it seems that per #511 it has worked previously, and curiously it seems that the exact same scenario actually worked fine in 1.22.2!
It does however not work from 1.23.1 onwards.

Below I have attached the full engine log from a successful run in 1.22.2.

I can verify stjen's result. I can't get -exec set db-follow-fork (or variants -gdb-set ...) to work in 1.31, but if I back up to 1.22.2 it works as expected. Please fix this.
