           Summary: SIGSEGV in versioninfo.c
           Product: Mono: Runtime
           Version: SVN
          Platform: x86
        OS/Version: Ubuntu
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: io-layer
        AssignedTo: dick at novell.com
        ReportedBy: gert.driesen at pandora.be
         QAContact: mono-bugs at lists.ximian.com
          Found By: ---

Using the attached repro to obtain the FileVersionInfo of an assembly emitted
using CSC results in a SIGSEGV.

Running it on MS and Mono/Windows works fine.

To reproduce:

1. extract the attached gzipped tar archive.
2. run 'mono test.exe'.

Expected result:

Successful execution.

Actual result:

Stacktrace:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
