I have a problem that is difficult to diagnose. I generated a sparse matrix and a vector, all the elements are allocated, if I run the function step by step in VS Code everything seems to work fine, but when I just run Julia crashes leaving behind the message in the image (I had to screenshoot it because it disappears as soon as Julia crashes)
The operation is a simple
A\b between a Sparse ComplexF64 non singular tridiagonal matrix A and a nonzero complex vector b
It seems to be a problem with the SuiteSparse, but I don’t understand it
in expression starting at none:1

Could it be an “out of memory” error?
I don’t think so… usually it gives me out of memory as an error, plus the matrices are relatively small (I made a domain decomposition implementation).
The other thing that is frustrating is that if the code crash there it’s done but otherwise it works like a charm and I do not understant how or why. Everything is deterministic up to that point in the code
