The constructors are referenced by the ModuleInfo. ModuleInfo is theoretically
unreferenced which will cause issues with --gc-sections, but as long as you
don't use --gc-sections that doesn't matter. (LDC has a workaround, IIRC)


The problem in this case is that the linker does not even attempt to link in
the object file though. The linker only looks at object files in a static
library if it still has some unresolved symbols. A solution is using the whole
archive linker option:

As you said this will result in bigger executables though.
