A bug of numeric::solve

Question

Consider

syms x f(x);
f = @(x) (x^2 - 4)^(1/2)/log(x^2)^2;

The command

solve(f(x)==0,x,'Real',true)

returns

ans =

  2
 -2

and I try

feval(symengine,'solve',f(x)==0,x)
feval(symengine,'numeric::solve',f(x)==0,x)
feval(symengine,'numeric::solve',f(x)==0,x,'AllRealRoots')

which return

ans =

[ 2, -2]

ans =

-1.9999947682667438275672111558379

and

ans =

[ empty sym ]

respectively.

Is this really a bug of numeric::solve?

Or I just missed some point in the commands.
