Has anyone noticed that Matlab has become more unstable under R2015b? In my use case I run some intensive data crunching and especially when trying to abort with CTRL+C, the system often crashes. I have done that countless times with the R2014b release and almost never had a problem.
I get the following crash details:

That new engine, can't deal with my ... methods
UPDATE 01 Feb 2016
The crash does NOT produce dump files, but I managed to reproduce the situation that generates the issue.
If I run the following code and I CTRL+C (you might need to try a few times before it crashes), then I get the APPCRASH:
for ii = 1:1e4
if mst.To % Problem is linked to this
The code loads a table of name mst and then checks that the column of the table meets some condition (I simplified down the code to the bare minimum). If I remove the condition with the dot indexing CTRL+C won't crash Matlab. Hence, it seems something wrong goes with the interaction of load and table indexing. The condition alone, on a previously loaded table, does not crash Matlab.


You have ... methods? Is that Evil Villain Laughter #7 that I hear in the background?
You can post some crash dump files. That would be helpful.
You can find crash dump files in the folder returned by the following command:

Support suggested to try the pre-release R2016a and I did not manage to crash Matlab on that. You can infer the rest.
