Global constructors don't work on aarch64

[ghaith]

Describe the bug
The global constructors segfault on arm architecures, they work fine with x86_64.

To Reproduce
Steps to reproduce the behavior:
The following code snippet is a minimal example that reproduces the issue:

FUNCTION main : DINT
    VAR i : DINT := 0; END_VAR
    WHILE i < 10 DO
        i := i + 1;
        mainProg();
    END_WHILE
END_FUNCTION


PROGRAM mainProg
VAR
    myFb_ref : REF_TO myFb := REF(myFb_inst);
END_VAR
    myFb_ref^();
    printf('mainProg executed$N');
END_PROGRAM

FUNCTION_BLOCK myFb
    VAR
        a,b,c : DINT;
    END_VAR
    a := a + 1;
    b := b + 2;
    c := a + b;
    printf('a: %d, b: %d, c: %d$N', a, b, c);
END_FUNCTION_BLOCK

VAR_GLOBAL
    myFb_inst : myFb := (a := 5, b := 10, c := 15);
END_VAR
