+Summary: execution of console hello world crashes if --optimize=all is used
+
+Description of Problem:
+A console program that is running well with default optimization is
+crashing when using --optimize=all with following output:
+
+dun3 at dun3$ mono --optimize=all md5.exe
+
+Unhandled Exception: System.TypeInitializationException: An exception was
+thrown by the type initializer for System.Console --->
+System.Reflection.TargetInvocationException: Exception has been thrown by
+the target of an invocation. ---> System.ExecutionEngineException: SIGILL
+in <0x00020> System.Collections.Hashtable:.ctor (Int32 capacity, Single

+
+in <0x00000> <unknown method>
+in <0x001b2> Md5MonoOptimized.Program:Main (System.String[] args)
+
+Steps to reproduce the problem:
+1. use this machine
+2. compile a hello world like this:
+using System;
+class Hello {
+ static void Main() {
+ System.Console.WriteLine("Hello World");
+ }
+}
+3. use --optimize=all
+
+Actual Results:
+Program crashes
+
+Expected Results:
+Hello world
+
+How often does this happen?
+always
+
+Additional Information:
+Steps are reproducable using version (selfcompiled):
+Mono JIT compiler version 1.1.15.20060610, (C) 2002-2006 Novell, Inc and
+Contributors. www.mono-project.com
+ TLS: __thread
+ GC: Included Boehm (with typed GC)
+ SIGSEGV: normal
+ Disabled: none
+
+and version (standard debian testing):
+Mono JIT compiler version 1.1.13.6, (C) 2002-2005 Novell, Inc and
+Contributors. www.mono-project.com
+ TLS: normal
+ GC: Included Boehm (with typed GC)
+ SIGSEGV : normal
+
+
+This only happens on my old linux machine, with these specifications:
+
+dun3 at dun3$ cat /proc/cpuinfo
+processor : 0
+vendor_id : GenuineIntel
+cpu family : 5
+model : 4
+model name : Pentium MMX

+
+dun3 at dun3$ cat /proc/version

+I can't repro this neither with HEAD, neither with the debian package.

+Sorry, I did some more testing and I stumbled across this line in the
+trace:
+
+in <0x0003a> I18N.Common.Manager:.ctor ()
+in <0x0003d> I18N.Common.Manager:get_PrimaryManager ()
+in <0x00000> <unknown method>
+
+So I figured it was some internationalization problem.
+
+And I found out this machine has following settings:
+LANG=de_DE at euro
+LANGUAGE=en_GB:en:C:de_DE:de
+
+changing them back to =C fixes this problem! But non the less, it is
+weird that the default optimization works without a problem with the
+above LANG settings and the all optimization fails.
+
+------- Additional Comments From vargaz at gmail.com 2006-06-13 11:58 -------
+I still couldn't repro this, could you try simplifying your LANG
+and LANGUAGE settings to simpler ones, like LANGUAGE is not set, LANG
+is de_DE etc ?
