Minimalist test case

// compile with gcc -fPIE -o my_issue.out my_issue.c
int main(){ return 0; }

Additional context?

I installed gef using

[osalbahr@c63 ~]$ bash -c "$(curl -fsSL https://gef.blah.cat/sh)"
[osalbahr@c63 ~]$ 

[osalbahr@c63 exp]$ gdb --version

I realized I don't have GDB 8.0 or higher.

If anyone's wondering, spack install gdb && spack load gdb did it for me.
