Building lmdb in Visual Studio 2017 produces warnings a memory error due to returning address of local variable from function mdb_strerror. Many warnings for integer truncation without using a cast. None of these seem severe. Will anyone clean this up?

After doing lots of profiling and debugging, we managed to determine that the problem was caused by our … [View More]

By examining the ContextCSNs it appears that all stalls at exactly the same point. Our configuration is a … [View More]
