It appears with 3.2.2 the address of a global var in dwarf already
contains the relocation.
Since fpdebug, does not retrieve any relocation info from lldb, it does
not adjust any addresses.
But with 3.3.1 it seems different.

The test app has 2 global vars.
They can be inspected if compiled with 3.2.2.
But compile with 3.3.1 and fpdebug send the following to lldb:
memory read --force --size 1 --format x --count 4 1008
memory read --force --size 1 --format x --count 4 1012
Looks like the offset within the exe, without relocation.
Was there an intentional change to introduce this?
git diff -w tags/release_3_2_2..main compiler/dbgdwarf.pas doesn't
really show any impactful changes between the two versions.
tf_dwarf_relative_addresses is also still set in
compiler/systems/i_darwin.pas
