           Summary: multithreading breaks phobos exceptions on mingw/gdc .23
           Product: DGCC aka GDC
           Version: unspecified
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: major
          Priority: P2
         Component: glue layer
        AssignedTo: dvdfrdmn at users.sf.net
        ReportedBy: default_357-line at yahoo.de


Consider the following code:
import std.stdio, std.thread, std.socket;

// intended to fail
void cause_throw() {
  Socket s=new TcpSocket(new InternetAddress("bogus", 80));
}

void main() {
  (new Thread(() { while (true) { } return 0; })).start;
  try cause_throw;
  catch (Exception e) { writefln("Exception: ", e); }
  writefln("Returning");
}

Now, if I comment the thread out, I get, as expected:
Exception: Unable to resolve etc.
Returning

However, if I leave it as it is, I get "Error: Unable to resolve etc.", and the
program freezes.

I was unable to find another gdc/mingw user to verify it.
Tried on a virgin 3.4.5/.23 and .22 and on a 4.0.2/.23 gdc MinGW setup.
The problem seems to be specific to gdc/win32.
