Hi Cygwin,

Many .Net programs that use to run correctly from a cygwin 1.7.9 console 
started throwing exceptions after updating to versions 1.7.10/1.7.11. I 
have noticed this problem on machines running Windows XP and Vista (32bits).

I attach a very small example that triggers the bug. The example is 
written in C#, and requires the .Net framework versions 2.0 or 3.5.

How to reproduce:

1) Compile the example with
         csc bug.cs

     The c# compiler (csc), can be usually found in
         C:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe
     or C:\Windows\Microsoft.NET\Framework\v3.5\csc.exe

2) Run the resulting bug.exe from a cygwin 1.7.10/1.7.11 console. It 
throws an exception.

3) Run bug.exe from a native windows console (or a cygwin 1.7.9 
console). It runs without producing any output, and without throwing any 
exceptions.

Be aware that the bug is not triggered if the example is compiled with 
the .Net framework 4.0.

Best regards,
Andrés Martinelli
