Fix this line

Code:

int UncompressedMaxSize = DataLength - (DataLength << 12) - (DataLength << 14) - (DataLength << 25) - 16;

It's probably wrong. Check the value you get from it.

It's the opposite of the compress code.
I use now 1000000 for testing.

Code:

char Output [1000000];
int success = uncompress((Bytef *)Output, (uLongf *)1000000, (const Bytef *)ChunkData.c_str(), (uLong)DataLength);

But then the uncompress crashes. Shouldn't i use c_str() or so?

I don't know. I don't know what ChunkData is, or what DataLength is, or what it holds.

You should definitely focus on this line though:

Code:

int UncompressedMaxSize = DataLength - (DataLength << 12) - (DataLength << 14) - (DataLength << 25) - 16;

I'm telling you, check the resulting value of that calculation, it's probably not what you expect. I expect a negative number.
Do you know what << means?
