Can anyone duplicate my matlab crash?

I am running a somewhat older version of matlab:
8.3.0.532 (R2014a)
When I run these commands, Matlab crashes:
a=zeros(19,1053);
tmp=min(a,[],2);
On the other hand, these commands do not cause a crash:
a=zeros(19,1052);
tmp=min(a,[],2);
In fact, there are a number of matrix sizes for "a" that can cause a crash, but for me, they all seem to have between 17 and 23 rows. In fact, the total number of elements in the matrix also has to be bigger than 20000.
I am running on:
Ubuntu 22.04.2 LTS
Intel(R) Xeon(R) Gold 6126 CPU @ 2.60GHz
I have tried this on two machines and it crashes on both.
The other machine is:
Ubuntu 22.04.1 LTS
Intel(R) Xeon(R) Gold 5118 CPU @ 2.30GHz

I'm not certain but it sounds like this may be Bug Report 1076354. One test you could do would be to transpose your array and take the max along dimension 1 as per the Workaround section of that bug report. If that doesn't crash that supports my hypothesis that it is that bug.

No problem encountered on two machines, but I don't have that release on my machine, and I think it is probably too old to run on my computer anyway. (I checked, and it appears I cannot even run that release on my computer. At least not without some work.)
It is entirely possible you have written a function called zeros, or perhaps a function named min. DON'T DO THAT! If not, then you might try contacting support. But a far better solution is to just upgrade your 9 year old release. This is not an existing MATLAB bug in current releases.
