Thank you for all your assistance with this Sven.
One trick I have been doing is writing equivalent programs in C/C++ to
see how Clang and MSVC convert them into equivalent assembly language.
It's providing some insights at least in regards to what works. My
first attempted fix (putting the jump table in the same section as the
actual code) unfortunately didn't work, so it's something more subtle.

Indeed - I'm not giving up! I installed Clang via LLVM. Which of
the EXE files is actually the assembler? It's not entirely clear
(no "clang-as", for example). (Although I trust it works!)
Simply check what FPC calls. ;)
I've got some ideas as to how to start debugging. I will solve
this puzzle!
There is a tool that converts DWARF to CodeView, you can use that to
debug with WinDBG.

Sven
