Doh! I think I just answered the question (of course it was After
hitting send)

So __ctors and __dtors are local to the program (address fix-up done by
genlds, etc...) ? This way the __ctors are only for the current program.
To add automatic handling of the global objects (for the kernel built
with TM and PROGRAM) would require that dll send the address of __ctors,
__ctors_end, __dtors and __dtors_end to the Program Manager.
This seems possible, but not likely in the very near future. Maybe I
can dig into it before January.
Mark, thanks for posting this code!

| Mark, This is an interesting issue. Initially, after reading your post, I was thinking that it would be easy to add this support to BrickOS. Of course, this is only partially correct. For NON Task Manager builds (therefore no Program manager), it is (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
