Unfortunately still no solution.
That's not quite true, because the log claims that the debug infos are being loaded,
but I also know that the log likes to lie.
Because it compiles with external TDS, the *.tds are deleted and yet the debug log claims that the debug infos are being loaded for this EXE/DLL/BPL, which can't be true because they are gone.
First of all, loading such packages with missing *.tds is really extremely slow
and then Delphi itself is too stupid to recognize the problem here, because they create a 1-byte DEBUG section in the actual compilation when the TDS is saved externally, but this "one" byte itself cannot of course contain any debug infos.
