I'm getting an EXCEPTION_ACCESS_VIOLATION and Julia continuing to run indefinitely until forced to quit. The example to reproduce and the error are below. I'm having trouble minimizing this example further. When I build the ODEProblem as close as possible "from scratch" I cannot reproduce this error. The exact error is slightly different if I run this multiple times but it always related seemingly to the garbage collector.

prob = sim.problem
u0 = prob.u0
p = prob.p
tmp2 = Enzyme.make_zero(p)
t = prob.tspan[1]
du = zero(u0)
_f = prob.f
_tmp6 = Enzyme.make_zero(_f)
tmp3 = zero(u0)
tmp4 = zero(u0)
ytmp = zero(u0)
tmp1 = zero(u0)
#_f(du, u0 , p, 0.0) #Forward pass of function; writes ~0.0 to du 

Enzyme.autodiff(Enzyme.Reverse, Enzyme.Duplicated(_f, _tmp6),
    Enzyme.Const, Enzyme.Duplicated(tmp3, tmp4),
    Enzyme.Duplicated(ytmp, tmp1),
    Enzyme.Duplicated(p, tmp2),
    Enzyme.Const(t))
Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

@m-bossart does this still err for you on latest enzyme/julia 1.10.5?

Yes I just tried with Julia 1.10.5 and Enzyme 0.12.35 and it still errors:

@m-bossart we've fixed another segfault on main, if you want to retry and see if that one resolved?

If not, we're gonna need a minimized version

Sorry for the delay and thanks for the reminder. I tried again, still failing with Julia 1.10.5/Enzyme0.13.3

Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

I am willing to simplify this further eventually, but I was having trouble before eliminating the dependencies and still hitting the failure. I'm also graduating in the next few months so might not get around to this for a bit.

If you want to close, I will re-open when I have a minimal example

FWIW, I have experienced a similar crash on Julia 11.1 with a very similar stack trace - and I do not use Enzyme in my project.

However, my code works on Julia nightly (1.12.0-DEV).
It seems JuliaLang/julia#56141 was the culprit.

btw @m-bossart I just fixed a potential segfault cause. Does this still err on latest enzyme?
