It appears we're in System.IO.Compression.DeflateStreamNative.ReadZStream and dying. That sounds like a BCL issue, so I'll move there.

However, without a repro case, this is significantly less likely to get fixed. 

Reporter, could you attach a sample showing the issue (if reproducible?)

I do not understand this bug report.   

How do we reproduce this?
