Mysterious rejection of the WER report IL

Question

I am trying to parse a Windows error report (Report.wer).

Here is part of the report:

Version=1
EventType=CLR20r3

... snip ...

Sig[0].Name=問題の署名 01
Sig[0].Value=myapp.exe
Sig[1].Name=問題の署名 02
Sig[1].Value=2.2.0.1
Sig[2].Name=問題の署名 03
Sig[2].Value=541bc264
Sig[3].Name=問題の署名 04
Sig[3].Value=System
Sig[4].Name=問題の署名 05
Sig[4].Value=2.0.0.0
Sig[5].Name=問題の署名 06
Sig[5].Value=4a275e12
Sig[6].Name=問題の署名 07
Sig[6].Value=2919
Sig[7].Name=問題の署名 08
Sig[7].Value=ef
Sig[8].Name=問題の署名 09
Sig[8].Value=System.IO.IOException

... snip ...

(where it 問題の署名means Problem Signature.)

Learned SO Decoding .NET clr20r3 exception parameters P1..P10 , I realized that:

• Build error Systemversion 2.0.0.0.
• Failure Marker Current 06002919.
• Malfunction of IL bias ef.

But the problem is the IL bias value ef.

The 06002919of method Systemdoes not IL_00ef.

Here is the definition of the method 06002919:

  .method /*06002919*/ assembly hidebysig

    IL_0050:  ret
  } // end of method NetworkStream::Poll

Am I misunderstanding something? How can I decrypt a WER report correctly?
