LZ4_compressHC Crashes #57

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Using the latest checkout LZ4_compressHC crashes. Attached is call stack.
Crash is memory management related.

OS: Windows
Compiler : Visual Studio 2012

Usage of LZ4_compressHC:

void CompressData(){
    for(int i = 0;i != DataTable.size();i++){
        if(DataTable[i].Compressed){
        char* Working = (char*)DataTable[i].Data;
        char* CompressTarget = new char[DataTable[i].Size];
        DataTable[i].CommitSize = LZ4_compressHC (Working, CompressTarget, DataTable[i].Size);
        DataTable[i].UpdateTarget->CompressedSize = DataTable[i].CommitSize;
        DataTable[i].Data = (unsigned char*)CompressTarget;
        delete[] Working;
        }
    }
}

Never mind i wasn't allocating enough for the output buffer. Everything seems 
to be working fine if i use LZ4_compressBound on the input buffer to determine 
output buffer size.
