digitalmars.D.learn - does dmd --build=profile-gc work with core.stdc.stdlib.exit()?

Hi,

I'm mem-profiling a multi-threaded program, and want it to exit 
early, so I added a call
```
core.stdc.stdlib.exit(-1);
```

in a loop in one of the thread.

However when the program reached this point, it seems hang: it's 
not exiting, and CPU usage dropped to 0%.

I'm wondering does dmd --build=profile-gc work with 
core.stdc.stdlib.exit()?

And where is the output report file, and the filename? I didn't 
see any report file generated in the current working dir.

BTW, can --build=profile-gc can intercept "Ctrl+C" and generate 
*partial* report file?

And what's the suggested proper way to do early exit, and still 
let --build=profile-gc generate reports?

Thanks!

I tried presss "Ctrl+C", and that cannot stop the program, it 
just hangs there.

I have to `kill -9 <pid>` it to get it stopped.

My build command is:
```
/dmd2/linux/bin64/dub build --build=profile-gc --config=... 
--compiler=dmd
```

Is there a profile-gc plugin function I can call in the middle of 
my program to generate *partial* report file?
