Hi,

consider this code:

import std.stdio;
import std.concurrency;
import core.thread;

void tryOpen()
{
  Thread.sleep(2.seconds);
  try {
    auto f = File("nonexistent");
  }
  catch (Exception e) {
    writeln("Could not open a file");
  }
}

void main()
{
  spawn(&tryOpen);
  readln();
}


On Linux, it works as expected, showing a "Could not open a file" after two or so seconds. On windows, however, the file opening gets blocked until a line is read from stdin.

Is this a feature or a bug? If it is a feature, it certainly is not documented.

Cheers,
Martin

Note that output to stdout is not good choice to check event order, because it's buffered. Try to flush stdout or write to stderr. Maybe it's actual problem.

Hi,

this is just for illustration, although I think that writeln flushes itself. I was checking it in a debugger after it suddenly hung my entire program.

Hi,

It works under Windows wenn compiled as a 64-bit program ( -m64 )
