           Summary: Catch ignored: JIT or verifier problem.
           Product: Mono: Runtime
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: JIT

The following sample makes "catch" not work, the runtime writes the message
"recheck failed" and after that instead of hitting a catch for Thread.Abort,
the program just terminates:

$ csharp
csharp> while (true) ;
recheck failed

At this point, hit control-c:
System.Threading.ThreadAbortException: Thread was being aborted
  at Class13.Host (System.Object& $retval) [0x00000] 
  at Mono.CSharp.InteractiveShell.Evaluate (System.String input) [0x00000] 

$

Notice that the execution of the above loop is protected by a:

try {
   ...
} catch (ThreadAbortException) {
   Thread.AbortReset ();
}

But the catch is never executed.   An alternative program does work though:

$ csharp
csharp> var a = false;
csharp> while (!a) ;

Hit control-c:
Interrupted!
System.Threading.ThreadAbortException: Thread was being aborted
  at Class1.Host (System.Object& $retval) [0x00000] 
  at Mono.CSharp.InteractiveShell.ExecuteBlock (Mono.CSharp.Class host)
[0x00000] 
csharp>  

So the catch is working in this case.
