No linking is done at compile time. I don't do any library loading manually. I
narrowed down which library changes the behaviour and looks at which symbols are
exported. All the symbols exported start with "SAL_" except for one symbol
called "findid"
Could it be that this findid symbol is replacing something else needed for RTTI?
