Issue on generation of additional empty MAT file

[shbang91]

Hello,

Thank you for maintaining this nice repo!

While doing my project, I encountered an issue with having an additional empty MAT file when saving data using Matlogger. The following statements are a high-level overview of the software architecture that I'm using.

I have a class A that has a Matlogger instance called logger_ (which is initialized with logger_ = XBot::MatLogger2::MakeLogger("/tmp/data")). Let's suppose that I create an instance of class A as A *a = new A(); and I repeatedly destruct delete a; and construct a = new A(); inside of a while loop which is always running in the background.
After deleting a once, killing the process (the while loop), and checking the data.mat, I always find there are two data.mat file in which one of them is empty.

My understanding from looking at the document of Matlogger is that once I create and delete class instance a, I should have just one data.mat file because logger_ dumps the data when it is destructed (which is automatically destructed when I delete a).

If you have any idea or guidance that could resolve this issue, I would really appreciate it.

Thank you,
