+Summary: exceptions not properly handled in therads with mono
+
+Given:
+/** startcode **/
+using System;
+using System.Threading;
+
+class TT {
+ public TT () {
+ tt_thread = new Thread (new ThreadStart (TT_Thread));
+ tt_thread.Start ();
+ }
+
+ public Thread tt_thread;
+
+ void TT_Thread ()
+ {
+ try {
+ throw new InvalidOperationException ();
+ } catch (Exception e) {
+ Console.WriteLine ("exception");
+ }
+ }
+}
+
+class Driver {
+ static void Main (string[] args) {
+ TT tt = new TT();
+ while (true) {
+ }
+ }
+}
+/** endcode */
+
+When running with mono results in:
+
+vladimir@rain[1385]% mono bar.exe
+exception
+
+Unhandled Exception: System.NullReferenceException: A null value was found
+where an object instance was required
+in <0x00072> 00 .TT:TT_Thread ()
+
+zsh: segmentation fault mono bar.exe
+
+When run with mint, it produces the expected 'exception' and then sticks
+around forever.
+
+Note that while the generated code PEVerify'd correctly under windows, it
+did not run correctly. It locked as soon as ./bar.exe was started and had
+to be killed from the task manager. Compiling bar.cs on windows gave the
+desired behaviour; copying the resulting (csc-compiled) assembly back to
+linux gave the same results as the mcs-compiled executable.
