Description

As of StaticArrays v1.0.1 and julia 1.5.3 I can cause a segmentation fault like this:

using StaticArrays

struct A{T}<:FieldVector{2,T}
       x::T
       y::T
end
A(1.,2)

Research direction

Start by running the Julia reproducer for the FieldVector constructor with StaticArrays v1.0.1 and Julia 1.5.3. Trace the constructor behavior for mixed argument types and verify that the case no longer segfaults and instead has defined behavior.
