Segmentation fault on large linear systems

[amontoison]

For JuMP-dev 2024, I wanted to give the elapsed time to solve a very large optimization problem with Ipopt and different linear solvers (MUMPS, SPRAL, MA27, MA57) but I got a segmentation fault for SPRAL:

This is Ipopt version 3.14.14, running with linear solver spral.

The culprit seems to be this function.

[jfowkes]

@amontoison I have no idea what that function even does 😢 Can you run it through the address sanitizer?

[amontoison]

@jfowkes I compiled SPRAL with --buildtype=debug tonight and I have these following errors:

[jfowkes]

@mjacobse do you have any idea what’s going on here or how we could best debug this?

[mjacobse]

Does it also segfault when running SSIDS serially? I.e. build without OpenMP or set OMP_NUM_THREADS to 1?

A way to reproduce this would be helpful, perhaps the offending matrix can be exported as .rb file?
