Hello!

Is it possible to start profiling on multithreaded app with Dmd?

https://issues.dlang.org/show_bug.cgi?id=14511 is open. I am 
doing wrong or why this program segfaults if compiled with 
profiler hooks?

import core.atomic;

shared struct S
{	
	uint counter;

	bool inc() shared
	{
		atomicOp!("+=")(counter, 1);
		return true;
	}
}

int main(string[] argv)
{
	S s;

	return 0;
}

Thank you!

As far as I know, profiling system doesn't work on multithreading 
programs correctly. At least, it has never worked for me. While 
closing the program, it creates problem always. But in a signle 
threaded environment, no problem.
