Matlab (2018a) crashes when trying to save fit

[maydinUCI]

Stan program runs without any issues. I can see the results, do plots with them etc. Matlab crashes if I try to save the structural matrix created by Stan. I'm wondering if anyone else has a similar problem or solution. Thanks

This crash was linked to CmdStan wanting to access expired timers during the save. Matlab tech support recommended upgrade to 2018b (or a downgrade to 2017b) would fix the problem. I tested Stan in Matlab 2018b and "fit" can be saved without causing a crash, although it generates a series of warnings (below). This does not impact on functionality since it is possible to recover the saved fit and work with it. So, I can confirm an upgrade to Matlab 2018b solves the problem.

Any resolution to this?

The cause of the crash was deleted timers associated with the fit output from Stan. The problem was specific to Matlab 2018a. An upgrade to 2018b or a downgrade to 2017b resolves the issue.
