The order of module initialization in CM3 is extensively traced. Try to
run your program with  @M3tracelinker and see what's wrong. The
code for module initialization is in

  cm3/m3-libs/m3core/src/runtime/common/RTLinker.m3

If the initialization does not work as expected, we must be missing
of overlooking some dependency there.

If you can provide a simple and small example that does not work,
I can probably have a look at it at the next weekend.

Sorry for the late answer,
