Size limit while working with memory stream


I am passing array of bytes and using Memory Stream for compression and decompression. Code execute successfully up to some limit like below array size less than 100mb. Once size of byte array grows I face issue while compressing with compression level ULTRA, If I change ULTRA to LOW then compression works. But then I face issue while decompressing. The error message is very generic as given below:

The execution has failed due to the bug in the SevenZipSharp.
Please report about it to http://sevenzipsharp.codeplex.com/WorkItem/List.aspx, post the release number and attach the archive.

It looks like it could be related to outofmemory exception. I am using version 0.64.3890.29348.
Guys any thoughts or workaround for this, please suggest.
