Using ForwardDiff with underdetermined initialization problems errors

[SebastianM-C]

Describe the bug 🐞

Using ForwardDiff to differentiate over solving an underdetermined initialization problem leads to an error during init.

Expected behavior

This should not error.

Minimal Reproducible Example 👇

Without MRE, we would only be able to help you to a limited extent, and attention to the issue would be limited. to know more about MRE refer to wikipedia and stackoverflow.

Additional context

This was also reported in SciML/SciMLSensitivity.jl#1190 (comment)

[AayushSabharwal]

This one is weird. The last time the error cropped up was a bug where the size of the initialization unintentionally changed. That isn't happening here, everything is identical modulo the type promotion to duals. So it's not immediately apparent what the issue is.

[ChrisRackauckas]

I can look into this one.

[ChrisRackauckas]

The right solution here is to add ForwardDiff overloads to LinearSolve.jl so it doesn't try to differentiate the solver. I think I talked with @oscardssmith about taking this on a bit ago.

[ChrisRackauckas]

It's equivalent to finishing SciML/LinearSolve.jl#434
