I am doing some analysis of some of my code using JET.jl.

When I use StaticArrays in the following way (below is a MWE), report\_call from JET is unhappy:

```julia
a=MVector(1,2,3,4,5)
b=MVector(6,7,8,9,10)
@report_call b[a.==2]

```

However, without static arrays, report\_call is just fine.

```julia
a=[1,2,3,4,5]
b=[6,7,8,9,10]
@report_call b[a.==2]

```

I will note that my code executes fine and is much faster when using StaticArrays for my use case, so I want to use it. Should I just ignore this apparent issue reported by JET or is there a better way to achieve what I’m after?

Edit: here is the report\_call output:

Could you show the output from `@report_call`?

Sure! Added to the original post.

Seems unnecessary, report a bug to StaticArrays.jl.
