Yes you do. Compile on 12.1, run on 12.1: it uses offset 0 meaning l_addr, no
_rtld_version_laddr_offset so it recalculates the address, all good. Now
upgrade to 12.2, it crashes because _rtld_version_laddr_offset is there so
assumes l_addr is already valid, and it is, but it is located at a different
offset - what is at offset 0 is no longer l_addr -> crash. It would need to be
recompiled on 12.2 to find l_addr at its new offset and use it correctly.
