StackOverflow with eigen

[mesonepigreco]

Dear developers, I found that the following code gives rise to a stack overflow:

using Bumper
using LinearAlgebra
 function trial(x)
       @no_escape begin
          T = @alloc(eltype(x), 2, 2)
          T .= 0
          T[1,1] = x
          T[2,2] = x
          eigval, eigvects = eigen(T)
          sum(eigval)
       end
end

julia> trial(2)

Generates the following error:

ERROR: StackOverflowError:

Am I using Bumper in the wrong way? My understanding is that the memory allocated inside @no_escape should not escape the block. Still, here, the block returns a scalar reduction of the allocated array, so the memory should not escape.

Is there another way to diagonalize a matrix allocated on the Bumper stack?

EDIT: Also, the error occurs in the line that calls eigen(T).
