           Summary: Mono 1.2.6 crashes with Segmentation fault
           Product: Mono: Class Libraries
           Version: 1.2.6
          Platform: i686
        OS/Version: Linux
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: CORLIB

Description of Problem:
Mono crashes with "Segmentation fault" message when trying to run assemblies
compiled by Microsoft Visual Studio 2005 C# compiler.

Steps to reproduce the problem:

1. Unarchive enclosed 'bug-reproduce.tar.gz'. There will be 4 files:
a) ShiftReduceParser.dll - this is a third-party DLL, which comes with
GPPG/GPLEX tools (http://plas.fit.qut.edu.au/gppg/). There are no sources for
this library.
b) pcsc.exe - Parallel C# compiler (this is a managed library, compiled by MS
Visual Studio 2005). Full source code is available here:
c) ParallelCSharp.AST.dll - part of Parallel C# compiler (this is also a
managed library, compiled by MS Visual Studio 2005). The source code is
available in the same archive as pcsc.exe
d) test01.pcs - This is a simple test file which we'll try to compile by

2. Run command
mono pcsc.exe test01.pcs

Actual Results:
pcsc.exe halts with "Segmentation fault" message

Expected Results:
On Windows it works fine. It should generate test01.cs and then call native
gmcs compiler and generate test01.exe file

How often does this happen?
