this program never finishes. it prints

foo
foo

and its window remains open, eating all available CPU power. if only one call to foo is made in main, everything is fine. so it is when the 'synchronized' statement is removed. tested on dmd 0.82, winxp sp1.

void foo()
{
synchronized
{
printf("foo\n");
}
}

void main()
{
foo();
foo();
}

Typically, one would need an object to synchronize upon, even if it's the class object where the synchronized keyword appears within.

For example, this version works as one might expect:

static Object o;

void foo()
{
  synchronized (o)
  {
     printf("foo\n");
  }
}

void main()
{

o = new Object();

foo();
foo();
}

I wonder if synchronized is even meant to parse for 'static' usage per your example? The online-reference section on "statements" does appear to indicate this is supported though ...

 SynchronizeStatement:
		synchronized Statement
		synchronized ( Expression ) Statement

Walter,

Is synchronized supposed to work with static methods? Currently, it really does produce some very odd process-termination behavior ...
