error in deflator

[Michael Hunley]

I am using Crypto++ 5.1 on Linux Redhat 8.0 under gcc 3.2.2.  I have a very 
recent cut of Crypto++ from cvs.  I know from previous posts that some bugs 
got fixed in the zdeflate code (some new and some rolled in from fixes in 
4.1).  However, I am still getting an error (and throw) in the release 
build.  The debug version works fine, as do both versions under WinXP 
compiled using MSVC6 sp 5 with processor pack.

I am using it to package up a signed, compress copy of a file to be 
downloaded from the internet.

The error:
zdeflate.cpp line 458: void CryptoPP::Deflator::ProcessBuffer(): Assertion 
'm_stringStart <(m_blockStart+m_blockLength) <= 1'

Usage:
        std::string outPath;
        ... // outpath set to the destination file
        ZlibCompressor  outFile(new FileSink(outPath.c_str(),true));
        ...// sbbCipherText filled with encrypted file data, throw if no data
        outFile.PutMessageEnd(sbbCipherText.begin(),sbbCipherText.size());
        // crash somewhere during this put
Is this a known issue?  Has anyone else had similar problems?  What info 
would help track it down?
