Enzyme execution failure

[swilliamson7]

With some code I have I'm hitting the following error:

You may be using a constant variable as temporary storage for active memory (https://enzyme.mit.edu/julia/stable/#Activity-of-temporary-storage). If not, please open an issue, and either rewrite this variable to not be conditionally active or use Enzyme.API.runtimeActivity!(true) as a workaround for now

Per advice posting it here without a MWE

Have you tried running with Enzyme.API.runtimeActivity!(true) as the error message recommends (maybe we need a better error message).

What is ShallowWaters.jl/src/time_integration.jl:953?

[swilliamson7]

I did indeed, adding that line led to a rather large GC error

[wsmoses]

The first errors should hopefully be fixed by #1278 (and if not reopen).

Can you oepn a different issue for the segfault?
