Vscode-cpptools: [GDB]Can’t hit the breakpoint in child process after "-exec set follow-fork-mode child"
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
include
include
int main()
{
pid_t pid = fork();
if (pid != 0) {
printf("Main process\n");
} else {
printf("Forked process\n");
}
return 0;
}

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.

I'm having the same issue. For anyone else here looking for the old version of vscode: https://code.visualstudio.com/updates/v1_22.

I was able to investigate this and see that this broke when this fix was introduced. I'm currently working on a fix for this.

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.
