Credit to @DavidADoran for reporting the problem https://github.com/MSOpenTech/redis/issues/376 and providing
the code to reproduce the bug.

Add notice to install VS2013 Update 5 to make sure it compiles properly.

Since the forked process allocates the memory from the system heap,
it must verify if the address is in the system heap or in the
redis heap before freeing it.
Changed dictRehash to NOOP when called by the forked process to avoid
extra processing that is not required when the forked process is
saving the dataset.

Replication (including diskless replication) requires persistence to be
available. This fix prevents a crash and returns "ERR unknown command" to
the slave.

stand-alone hiredis repository.

[Fix] 32 bit memory heap limit to 1 GB due to contiguous block allocation

Fix for issue #361.

Errors are now written to the Event log if they occur before the file logging

Rollbacked setLogFile method name.

Windows version doesn't change at run time, call IsWindowsVersionAtLeast once
and store the result.

Replaced tabs with spaces. Removed .gitignore from the test\tmp folder and
added the test\tmp folder path to the .gitignore in the root.

If the child process exists without closing the socket first, a socket read
error occurs on both the parent process and the connected slave.
