Mysterious silent crashed on windows when solving within threads

[Omar-Elrefaei]

I accidentally came across these weird crashes that are kind of consistent. Surprisingly, This doesn't seem to be replicable on Linux.

MWE:

using LinearSolve, Random, LinearAlgebra

function buggy_solve(seed)
    Random.seed!(seed)
	n = 4
	m = 4
	a = randn(m,m)  
    c = randn(n,n)

	b = randn(m*n)
	A = kron(c, a)

	linprob=LinearProblem(A, b)
	println("checkpoint 1")
	target = solve(linprob).u
	println("checkpoint 2")
end

Threads.@threads for i in 10:13
	buggy_solve(i)
end

when saved in weird-threads-bug.lj and ran with julia --threads auto weird-threads-bug.jl julia itself just crashes with a non-zero exit code.
or when run from a repl, I just find myself dropped back at the shell.
When run from julia as run(``) (or python) it reports 3221225477 exit code, which I guess is a translated version of the -1073741819 that CMD returns. Numerous search results point to that being 0xC0000005 in hex which stands for STATUS_ACCESS_VIOLATION

screenshot demonstration

 (first is a run with `--threads` demonstrating the crash and second is without and the script succeeds)

I've tested on linux on Julia v1.7.1 and I don't seem to be able to trigger it.
Unfortunately I can't test on Julia v1.9 on windows because of corporate policies (I don't have a windows machine but I can borrow one from a family member if needed)

I've no idea how to look into this further. This is not blocking or essential for me, just came across it by chance, so no need to feel urgency.

This looks like it's fixed on LinearSolve v2 with Julia v1.9.
