FishNet | FishNet: Unity Networking Evolved | Game Engine library

My jobs have been suffering due to segmentation faults when calling glmnet (downloaded from here:http://web.stanford.edu/~hastie/glmnet_matlab/download.html) from my MATLAB code. I call the glmnet routine thousands of times. I have noticed the following peculiarities about the problem occurence:

1. The problem is more frequent when the size of my input matrices are larger.
2. I use both gaussian and poisson distribution in separate jobs, and I notice that the problem is more frequent when fitting the Poisson distribution (which also takes usually longer to converge, so might involve more loops internally?) Since there haven't been reports of segmentation faults for the R version for these two distributions, my suspicion is that the problem, likely a memory leak, might lie in the mex interface rather than the core glmnet Fortran code, which I am pasting below. Any insights into where a memory leak might be happening is greatly appreciated! Apologies for the lengthy code dump.

Thanks!

I would like to select polygons from one simple feature collection that intersect a polygon in another sf collection. Here is a reproducible example:

I have a dataframe of lines, each line with a x/y start and end coordinate. These lines describe a grid / fishnet as you can see in the minimal example below. Regrettably, the grid is not perfectly even and every so often shifted a bit.
